Question

A magnetic field directed into the page changes with time according to B = 0.0240t² + 1.40, where B is in teslas and t is in seconds. The field has a circular cross section of radius R = 2.50 cm (see figure below). 

 (a) When t = 1.65 s and r2 = 0.020 0 m, what is the magnitude of the electric field at point P₂?

 (b) When t = 1.65 s and r2 = 0.020 0 m, what is the direction of the electric field at point P₂?
