Point charges of 28.0 µc and 35.0 µc are placed 0.250 m apart. (a) at what point (in m) along the line between them is the electric field zero?m away from the 28.0 µc charge (b) what (in n/c) is the electric field halfway between them? (enter the magnitude.)

A1000-kg weather rocket is launched straight up. the rocket motor provides a constant acceleration for 16-s, then the motor stops. the rocket altitude 20-s after launch is 510-m. you can ignore any effects of air resistance. a. what was the rocket’s acceleration during the first 16-s? b. what is the rocket’s speed as it passes through a cloud 5100-m above the ground?

Anybody wanna ? (picture included? )
