Consider the configuration of particles shown below. These four particles form a square in the x-y plane with sides of 5.2 cm. Particle 1 is an electron, particles 2 and 3 are protons, while particle 4 is a neutron. The electron moves in the +y direction at 1.1x10⁵ m/s, while the other three particles are essentially motionless.

a) Find the electric field at particle 1’s location and the electric force acting on it.

b) Find the electric potential at particle 4’s location.

In addition, a very long wire carrying 23 mA of current in the +y direction sits 26 cm to the left of particles 1 and 2.

c) Find the magnetic field at particle 1’s location and the magnetic force acting on it.

Also, there is a conducting ring surrounding (but not in contact with) the current-carrying straight wire.

d) The direction of the current induced in this ring by the current in the straight wire is

clockwise
counterclockwise
neither; there is no induced current

Over a period of one second, the current in the straight wire is reduced to zero.

e) During that one second time interval, the direction of the current induced in the ring is

clockwise
counterclockwise
neither; there is no induced current

Then, the curent is switched back on over a period of one second, only now it runs downward (instead of up the wire as before).

f) During that one second time interval, the direction of the current induced in the ring is

clockwise
counterclockwise
neither; there is no induced current
