Two electrons are separated by 2.00 nm. What is the magnitude of the electric force each electron exerts on the other?

What are the phases shown in a and d called?

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?
