Coulomb's Law
1. When a charge experience a force, there will be a ________ field developed.
- A. Magnetic
- B. Electric
- C. Static
- D. All of these options are correct
View answer and explanation
Answer: B. Electric
A charge experiences an electric force E, so an electric field is associated with any charge. A magnetic field is produced only by moving charges, so a stationary charge develops an electric field, not a magnetic one. Hence B is correct.
Capacitors
2. A capacitor initially at discharges with time constant . What is its voltage after ?
- A.
- B.
- C.
- D.
View answer and explanation
Answer: B.
During discharge, V.
Electric Potential
3. Two charges one of which is and second one is are separated by . The electric potential is zero at a point (ETEA 2022)
- A. from Q
- B. from Q
- C. from Q
- D. from Q
View answer and explanation
Answer: B. from Q
Let the charges be and , separated by distance cm. We need a point where the net potential is zero: + k = 0. Assuming the point lies on the line joining the charges, outside the smaller charge (since they have opposite signs), let the distance from be x and from be (x - 100) if outside on the side of , or (100 - x) if between. For zero potential, we need k(3/x) + k(-1/( (assuming point between them, = x, = 100-x). Then 3/ => => 300 - => => cm. So the point is from the + charge. Hence, option B is correct.

Common questions about Electrostatics practice
How many Electrostatics MCQs are available on DIFF. MDCAT?
The current Electrostatics question bank contains 910 practice MCQs across 4 topics. This is the bank size, not the length of one test. Choose your topics and a question count from 1 to 180, limited by the questions available in those topics.
Which topics does the Electrostatics quiz cover?
The selectable topics are Coulomb's Law, Electric Field, Electric Potential, Capacitors. Use Select all for a broad chapter drill, Clear to start a focused selection, or choose individual topics. Questions are drawn from your chosen topics, so you can target a weak concept before returning to a wider test.
How do I build a custom Electrostatics test?
Open the chapter builder, select one or more topics, enter your question count, and choose Tutor Mode or Timed Exam. The available-question total updates with your selection. Start Test generates a shuffled drill; you do not have to follow a fixed Quiz 1 or Quiz 2 sequence.
What is the difference between Tutor Mode and Timed Exam?
Tutor Mode gives feedback and an explanation after you choose an option, and you can change or clear that choice. Timed Exam runs a countdown and keeps explanations hidden until submission. Both modes let you move between questions, use the paper map, and submit for a complete review.
How do I review and download my Electrostatics quiz?
Select Submit Quiz, then Submit & View Explanations. The review includes every question in your test, all options, your selection, the marked correct answer when a key is available, and the explanation. Download PDF saves a paginated review; Download Review saves an HTML copy you can open in a browser. The review also includes DIFF. MDCAT community links.
How should I use Electrostatics MCQs to improve?
Start with a short tutor drill on one of these topics: Coulomb's Law, Electric Field, Electric Potential. Read the explanation for incorrect and uncertain answers, revise the relevant textbook section, and retry before taking a timed drill. Compare your reasoning with the answer key rather than memorising the option letter.
