Asolenoid has a radius rs = 14.0 cm, length l = 3.50 m, and ns = 6500 turns. the current in the solenoid decreases at the rate of 79.0 a/s. a circular coil with a single turn and radius rc = 20.0 cm encircles the solenoid with its plane perpendicular to the axis of the solenoid. determine the magnitude of the average induced electric field in the coil.

E = 58.7 V/m

Explanation:

As we know that flux linked with the coil is given as

here we have

now we have

now the induced EMF is rate of change in magnetic flux

now for induced electric field in the coil is linked with the EMF as

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

if they have a finite resultant
