Two point charges are on the x-axis.  Charge q1 = 5.00 uC is at the origin and q2 = -3.00 uC is at x = 0.350 m.  a)  Find the magnitude of the electric field at a distance of 0.450 m directly above q2.

A 3.00 uC point charge is released from rest 0.450 m away from a 5.00 uC point charge.  If the 3.00 uC point charge has a mass of 0.002 kg,  what is its initial acceleration? Ignore gravity.

A proton having a speed of 3.0 × 10^6 m/s in a direction perpendicular to a uniform magnetic field moves in a circle of radius 0.20 m within the field.  What is the magnitude of the magnetic field? (e = 1.60 × 10^-19 C, mproton = 1.67 × 10^-27 kg)

A ball is thrown straight upwards with a speed of 15.0 m/s and is caught when it comes back to the same point.  b) How high does the ball go?

A flat rectangular loop of wire is placed between the poles of a magnet. It has dimensions w = 0.60 m and L = 1.0 m, and carries a current I = 2.0 A. The magnetic field due to the magnet is uniform and of magnitude 0.80 T. The loop rotates in the magnetic field and at one point the plane of the loop makes a 30° angle with the field. At that instant, what is the magnitude of the torque acting on the wire due to the magnetic field?

Find the direction (relative to the positive x-axis) of the resultant of the vectors shown if: V1 = 38, V2 = 19, and V3 = 10

Because saving and investment are equal for an economy, saving and investment must be equal for each person in the economy.

The U.S. government debt is owed to those who have purchased the bonds sold by the government.
