The electric potential at a distance of 1.2 m from a 7.5 µC point charge is 8.1 × 104 V. This can be calculated using the formula for electric potential, which is given by V = kq/r, where V is the electric potential, k is the Coulomb's constant, q is the charge of the point, and r is the distance from the point. Plugging in the values, we get V = (8.99 × 109 Nm2/C2)(7.5 × 10-6 C)/(1.2 m) = 8.1 × 104 V. Therefore, the electric potential at a distance of 1.2 m from a 7.5 µC point charge is 8.1 × 104 V.
