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 1C

This 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

Best 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.
