A parallel plate capacitor has its plates separated by 0.5 mm of air. The area plates is 2 m? and they are charged to a p.d.of 100 V.The plates are pulled apart untill they are separated by1 mm of air.Assuming the p.d. to remain unchanged, what is the mechanical force experienced the plates?

Two long straight wires are oriented parallel to each other with a small separation. The two wires experience a repulsive force between them. You examine one of the wires and find it has an electric current running through it. What must be true of the other wire? O It has zero electric current O It has a net positive charge O It has an electric current in the same direction as the first wire O It has an electric current in the opposite direction to the first wire

Inductance is often described as . (circle all that apply) The ability of a component to oppose a change in current The relationship between magnetism and current The ability of a component to store energy in an electromagnetic field The ability of a component to oppose a change in voltage

A charged particle moves into a region of uniform magnetic field, goes through half a circle, and then exits that region. The particle is either a proton or an electron (you must decide which). It spends 130 ns in the region. What is the magnitude of B? Give your answer in T.

Q5/ An electric field of 8.5 x 105 V/m is desired between two parallel plates each of (7 cm x 8 cm) and separated by 3.5 mm of air. What charge must be on each plate? What is the value of energy stored in the capacitor? A dielectric insulator has been inserted between the two plates.What is the value of K for this insulator in order to double the charge on the plates?

*10. A moving particle encounters an external electric field that de- creases its kinetic energy from 9520 eV to 7060 eV as the particle moves from position A to position B. The electric potential at A is -55.0 V, and the electric potential at B is +27.0 V. Determine the charge of the parti- cle. Include the algebraic sign (+ or -) with your answer.
