Answer:
The electric potential at a point due to a point charge is given by the formula V = kQ/r, where V is the electric potential, k is Coulomb’s constant (8.99 x 10^9 Nm2/C2), Q is the charge and r is the distance from the charge to the point.
In this case, we have two charges, so we can find the electric potential at a point 35cm away from each charge and then add them together to find the total electric potential at that point.
The electric potential due to the 2.3mc charge is V1 = kQ1/r1 = (8.99 x 10^9 Nm2/C2)(2.3 x 10^-6 C)/(0.35m) = 5.88 x 10^4 V.
The electric potential due to the -3.4mc charge is V2 = kQ2/r2 = (8.99 x 10^9 Nm2/C2)(-3.4 x 10^-6 C)/(0.35m) = -8.72 x 10^4 V.
The total electric potential at a point 35cm away from both charges is V = V1 + V2 = (5.88 x 10^4 V) + (-8.72 x 10^4 V) = -2.84 x 10^4 V.
