Question

Two particles carrying charges gn and q2 are separated by a distance r and exert an electric force FE on each other. Part A If gh is doubled, what change must you make to one of the other variables in order to keep the magnitude F constant? There is more than one answer Check all that apply. should be doubled. □ r should be changed to r/v2 should be halved. r should be changed to v2r □ should be changed to □ r should be halved should be changed toa/v/2 r should be doubled

Answer 1

Force= kq1q2/r²

if q1 is doubled then you could possibly make 2 independent changes to keep force constant.

Either half the q2 charge or increase the distance between √2 times .

Answer; 3rd and 4 th option

q2 halfed

r change to √2r
