Which is halfway between the charges

Reference no: EM139164

Q1. A pipe open at one end only has a fundamental frequency of 237 Hz. A second pipe, initially identical to the first pipe, is shortened by cutting off a portion of the open end. Currently, when both pipes vibrate at their fundamental frequencies, a beat frequency of 17 Hz is heard. How many centimeters were cut off the end of second pipe? The speed of sound is 233 m/s.

Q2. The two charges are separated by d = 2.30 cm. (Let q1 = -14 nC and q2 = 26 nC.)

(a) Find the electric potential at point A.

(b) Find the electric potential at point B, which is halfway between the charges.
