Question

An electron (9.11 x 10-31 kg) is placed at rest in a region containing a uniform electric field ⃗E and a uniform magnetic field of B⃗=(1.50T ) ^ i+(−2.80T) ^ j+(−0.70T) ^k . The electron reaches a velocity v=3400m/s ^ j after 0.200 nanoseconds have passed.

a. Find the electric field. ________________________

b. If the electric field is being produced by a parallel plate capacitor with square plates that are 0.30 m on each side and separated by 0.300 mm by a paraffin dielectric, find the voltage across the capacitor plates, the charge on the capacitor, and the capacitance.

V = ________________________

Q = ________________________
