Q4PhysicsUnit 11: Electrostatics
The voltage required to balance an oil drop carrying 10 electrons between the plates of a capacitor which are 10mm10 \mathrm{mm} apart, is (Given mass of the oil drop= 32×1015kg,e=1.6×1019C)\left.\mathbf{3} \cdot \mathbf{2} \times \mathbf{1 0}^{-\mathbf{1 5}} \mathbf{k g}, \boldsymbol{e}=\mathbf{1 . 6} \times \mathbf{1 0}^{-\mathbf{1 9}} \mathbf{C}\right)
Q5PhysicsUnit 11: Electrostatics
The top of the atmosphere is about 400 kV with respect to the surface of the earth, corresponding to an electric field that decreases with altitude. Near the surface of the earth, the field is about 100Vm1100 V m^{-1} Still, we do not get an electric shock as we step out of our house into the open house, because (assume the house to be a steel cage so that there is no field inside)

Q13PhysicsUnit 11: Electrostatics
A ball of radius R carries a positive charge whose volume charge density depends only on the distance r from the ball's centre as: ρ=ρ0(1rR)\rho=\rho_{0}\left(1-\frac{r}{R}\right) where ρ0\rho_{0} is constant. Assume ϵ\epsilon as the permittivity of the ball. Then the magnitude of the electric field as a function of the distance r outside the ball is given by :

Frequently asked questions

How long should a Electrostatics mock test take?

For a topic-level test, aim for 20–30 minutes. For a full subject mock, allow 60–90 minutes to mirror JEE timing.

What is a good score on a Electrostatics mock test?

Aim for 70%+ accuracy initially, then push toward 85%+ as your exam date approaches. Review explanations for every wrong answer.

Does Goodmarks score mock tests automatically?

Yes. Each MCQ is scored instantly with the correct answer and explanation shown after submission.

Can I retake the same mock test?

Pro users can generate new question sets by topic. Reattempting the same questions after a gap is excellent for retention.
