a) Typical electric fields in thunderstorms average around 10⁵ V/m. Consider a (roughly) cylindrical thundercloud with height 10 km and diameter 20 km and assume a uniform electric field of 10⁵ V/m. Find the electrical energy contained in the cloud (2 s.f.).

b) For the same thundercloud and imagining that the electric field points vertically downwards, calculate the minimum charge on a 5-mg raindrop that would cause it to accelerate upwards (2 s.f.). (Enter the magnitude of the charge into D2L to check your answer, but the sign is important too in your written solution.)

An electron is placed in a region with a 1010 V/m electric field directed in the positive x-direction. The electron escapes this region after traveling 14.0 cm. What is the kinetic energy of the electron? What is the particle's velocity? Will a proton placed at the same initial position and traveling through a similar 14.0 cm path acquire the same amount of kinetic energy? Will the proton experience the same change in velocity? Why or why not? I have seen...

Near the surface of the Earth there is an electric field of about 150 V/m which points downward. Two identical balls with mass 0.407kg are dropped from a height of 2.29m , but one of the balls is positively charged with q1 = 338?C , and the second is negatively charged with q2=-338?C . Use conservation of energy to determine the difference in the speeds of the two balls when they hit the ground. (Neglect air resistance.)
