(1) There are four charged particles, located at coordinates (#1, #1). All four are positively charged. Use the principle of superposition to find the vector field representing the electric
field generated by these particles on a negatively charged particle. Is it conservative? If so,
what is the potential function?

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?
