Hello!!!
Hope you are doing great!!!
given, edge of a cube= a
Workdone=force * displacement
force=1/4πε0 *q^2/r^2
displacement for the given cube=a/2
by substituing the values, We get
Workdone for 8 charges to be moved is
8(1/4πε0 *q^2/a^2)*a/2
by solving the above equation we get,
W=q^2 /πε0a Joules
Hope it helps!!!
