+3 μC and -5 μC respectively. The electric potential at the surface of the smaller sphere is to be calculated.
We can use the formula for electric potential due to a point charge:
V = kq/r
where V is the electric potential, k is Coulomb's constant (9 x 10^9 Nm^2/C^2), q is the charge, and r is the distance from the point charge.
For the smaller sphere, the charge q = +3 μC and the radius r = 1 cm = 0.01 m. The distance from the point charge to the surface of the sphere is equal to the radius of the sphere, so we can write:
V = kq/r = (9 x 10^9 Nm^2/C^2) x (3 x 10^-6 C) / (0.01 m) = 2.7 x 10^5 V
Therefore, the electric potential at the surface of the smaller sphere is 2.7 x 10^5 V.
