Here, q = 1.6 × 10-19 C, m = 1.67 × 10-27 kg, = 0.7 T/s, and r = = 1 × 10-2 m.
The magnetic field in the figure is decreasing at the rate of 0.7 T/s. Protons are at rest at points a, b, c, d.
(a) What is the magnitude of the acceleration of a proton at rest at point c? Express your answer as an integer and include the appropriate units.
(b) What is the direction of the acceleration of a proton at rest at point c?
