Question

the length of rod is l, charge density is lambda c/m find the electrostatic force exerted by ring on rod​

Answer 1

Answer:

V

Explanation:

Electric field due to rod 1 at a distance

′

d

′

is given by -

due to electric field from rod 1 rod 2 experiences an electric force.

So, force per unit length is given by (f)

f=

L

F

=Eλ (λ : charge/ length)

From (1),

f=

d

2kλ
