Two charges 1C and -4C exists in air. What is the direction of force?(a) Away from 1C(b) Away from -4C(c) From 1C to -4C(d) From -4C to 1CThis question was addressed to me by my college director while I was bunking the class.This key question is from Coulomb Law topic in chapter Electrostatic Fields of Electromagnetic Theory

Answer» RIGHT option is (c) From 1C to -4C

The EXPLANATION: SINCE the charges are unlike, the force will be ATTRACTIVE. Thus the force directs from 1C to -4C.
