2. The strength of the uniform electric field between two parallel conducting plates separated by 4.00 cm is 7.50×10⁴ V/m . a) What is the potential difference between the plates?  b) The plate with the lowest potential is taken to be at zero volts. What is the potential 1.00 cm from that plate (and 3.00 cm from the other)?  

5. What must be tge charge of an isolated spherical conductor 30.0 cm in diameter to produce an electric field of 150 N/C just outside the surface?

4. A closed irregular surface encloses a net charge of 1.50 x 10 C. What is the net electric flux through the surface?

The crane is pulling up with a force of 216N and the box is being down by gravity with a force of 127 N draw a free body diagram and determine what the net force is and in what direction it is acting.

2. A long straight wire has a charge per unit length of 3.00 x 10^-12 C/m. At what distance from the wire is the electric field equal to 0.600 N/c.

The elevator and its passenger together have a mass of 1200.0 kg. While moving upwards, the elevator slows down from 10 m/s to 0 m/s in 2.5 seconds. How much tension (in N) must be in the cable during that time? (Use g=10N/kg)

A crane is raising a box of Star Wars action figures so it can be put on a barge to be shipped to its eager recipients. The crane is pulling up with the force of 216N . The box is being pulled down by gravity with a force of 127N . Draw a Freebody diagram and determine what the net forces and then what direction it is acting.
