(a) Find the electric potential at (4.00, 0) m, assuming the electric potential is zero at infinity.

a) at the point (4 , 0)
electric potential = electric potential due to -2.1 uC + electric potential due to 3.2 uC
electric potential = 9 *10^9 * 10^-6 * (-2.1/4 + 3.2/sqrt(3^2 + 4^2))
electric potential = 1035 V
the potential at the point (4 ,0 ) is 1035 V
b)
for the 3.5 uC Charge
work needed = V * Q
work needed = 1035 * 3.5 *10^-6
work needed = 3.62 *10^-3 J
