Explanation / Answer

here,

sepration between the charges , r = 0.43 m

the number of electrons , N = 3.7 * 10^13 electrons

charge on each electron , Q = e * N

Q = 1.6 * 10^-19 * 3.7 * 10^13 C

Q = 5.92 * 10^-6 C

the magnitude of electrostatic force between the sphere , F = K * Q^2 /r^2

F = 9 * 10^9 * ( 5.92 * 10^-6)^2 /0.43^2 N

F = 0.73 N

a)

both the sphere have opposite charges

so, they will attract each other
