For problem 25 part b, calculate the potential at point P in volts using a value of Q2=-3.17 Q1 instead of the value in the stated problem. Answer in 5 sig figs!!

25 A plastic rod has been bent into a circle
of radius R = 8.20 cm. It has a charge Q₁ =
+4.20 pC uniformly distributed along one-
quarter of its circumference and a charge
Q2 = -6Q₁ uniformly distributed along the
rest of the circumference (Fig. 24-44). With
V = 0 at infinity, what is the electric potential at (a) the center C of
the circle and (b) point P, on the central axis of the circle at dis-
tance D = 6.71 cm from the center?
