Question

Two identical small conducting spheres having unequal positive charges `q_1` and `q_2` are separated by a distance r. If they are now made to touch each other and then separated again to the same edistance, the electrostatic formce between them in this case will be
A. less than before
B. same as before
C. more than before
D. zero

Answer 1

Correct Answer - c
`F_(1) prop q_(1)q_(2) rArr F_(2) prop((q_(1)+q_(2))^(2))/(4)`
Thus, `F_(2) gt F_(1)`
