Question

Assume two negative charges are placed close to each other, with one charge fixed and one charge free to move. The free charge will: O a accelerate away from the fixed charge. b. move closer to the fixed charge. Og C. orbit the fixed charge in a circular motion. d. remain stationary.

Answer 1

Q 1.

Two same kind of charges repel each other so free charge will accelerate away from the fixed charge .

correct answer is (a)

Q.2

Soaking paper in salt water will conduct electricity as salt walter has a lot free ions .

so correct answer is (a)

Q.3

gauss’ law is given by (closed surface integral)E.dA = Q_inclosed/$\varepsilon$

so electric flux = inclosed charge/ epsilon

so correct answer is (a)

Q.4

potential energy = work done by electric field

if we make the charge unit then

electric potential = work done by electric field on unit charge.

so correct answer is (a)
