A small ball of mass, m = 6.10 × 10-9 g, has acquired an excess charge. The ball is then placed between two parallel plates spaced x = 3.75 mm which have a potential difference of V = 2510 V applied across them. In this configuration the ball appears to be motionless or floating in between the plates. What is the overall charge on the ball? Calculate the number of electrons, ne, the ball has either gained or lost. The acceleration due to gravity is g = 9.81 m/s2, and the elementary unit of charge is e = 1.60 × 10-19 C.

Awind turbine is initially spinning at a constant angular speed. as the wind's strength gradually increases, the turbine experiences a constant angular acceleration 0.173 rad/s2. after making 2870 revolutions, its angular speed is 132 rad/s. (a) what is the initial angular velocity of the turbine? (b) how much time elapses while the turbine is speeding up?
