Question

# A charge is divided into two parts of and . If the Coulomb repulsion between them when they are separated, is to be maximum, the ratio of should be:

A
B
C
D
Medium
Solution
Verified by Toppr
Correct option is A)

## Let parts are separated at a distance of 'd'So repulsion force,here, Q and d are constant so for maximum force differentiate the force w.r.t q,For maximum force,
