Question

Within the green dashed circle shown in the figure below, the magnetic field changes with time according to the expression B = 4.00t³ − 2.00t² + 0.800, where B is in teslas, t is in seconds, and R = 2.65 cm.

a) When t = 2.00 s, calculate the magnitude of the force exerted on an electron located at point P₁, which is at a distance r₁ = 5.30 cm from the center of the circular field region.

b) At what instant is this force equal to zero? (Consider the time after t = 0 s.)
