You have a charge, Q, a distance 0.35 m from where you are measuring its electrical properties. You measure an electric field strength of 3.5 x 106 N/C.

What is the charge, Q?

What is the electric potential at this point?

What would happen to the field strength if the charge was moved to a distance of 0.70 m? How would the potential change?

At 0.70 m, what is the potential energy available to an electron due to charge Q's influence?

Suppose a force of 60 n is required to stretch and hold a spring 0.1 m from its equilibrium position. a. assuming the spring obeys hooke's law, find the spring constant k. b. how much work is required to compress the spring 0.5 m from its equilibrium position? c. how much work is required to stretch the spring 0.6 m from its equilibrium position? d. how much additional work is required to stretch the spring 0.1 m if it has already been stretched 0.1 m from its equilibrium? a. kequals 600
