Two point charges with charges of #8.4xx10^-6# are brought close to each other. (a). Sketch this and show the direction of the electric force? (b) If the point charge on the left feels a force of #0.66N,# calculate the distance, #r,# between them?

#0.96m#

#a.# as two like charges are present in this case,they will try to push the apart from each other.

#b.# we know electrostatic force acting #F# due to two like charges of #q# separated at a distance of #r# is given as,

#F= 1/(4 pi epsilon) (q*q)/(r^2)#

Given, #F=0.66,1/(4 pi epsilon)=9*10^9,q=8.4*10^-6#

so,putting the provided value we get,

#r=0.96 m#
