Question 861: Electrostats & Capacitance

Question

When a charge of $$3 ~\mathrm{C}$$ is placed in uniform electric field, it experiences a force of $$3000 \mathrm{~N}$$. Within this field, potential difference between two points separated by a distance of $$1 \mathrm{~cm}$$ is

Accepted Answer

Electric force, $$F=q E$$ and potential difference, $$\mathrm{V}=\mathrm{Ed}$$
$$	herefore \quad \mathrm{V}=\frac{\mathrm{Fd}}{\mathrm{q}}=\frac{3000 	imes 10^{-2}}{3}=10 \mathrm{~V}$$
[Note: Framing of question is modified to arrive at the correct answer.]

Answer

$$10 \mathrm{~V}$$

Answer

$$90 \mathrm{~V}$$

Answer

$$1000 \mathrm{~V}$$

Answer

$$3000 \mathrm{~V}$$
