Question

For the situationdescribed in Figure P31.32, the magnetic field changes with time according to the expression B = (4.00t³ - 4.00t² + 0.800) T, and r2 = 2R = 5.00 cm.


(a) Calculate the magnitude and direction of the force exerted on an electron located at point P2 when t = 2.00 s.
counterclockwise
clockwise

(b) At what time, other than when t = 0, is this force equal to zero?

Dear student, please refer to the question below.
Question:

For the situation described in Figure P31.32, the magnetic field changes with time according to the expression B = (10.00t. 2.002 + 0.800) T, and r2 = 2R = 5.00 cm. Figure P31.32 (a) Calculate the magnitude and direction of the force exerted on an electron located at point P2 when t 2.00 s. O clockwise counterclockwise (b) At what time, other than when t-0, is this force equal to zero?
