A small plastic sphere of mass (m) has a charge q = 2.0 C. An upward pointing uniform electric field of magnitude 5.0 × 10-3 N/C supports and balances the weight of the sphere. Find the mass (m) of the sphere.

A copper ring of radius R lies in a uniform magnetic pointed into the screen, as shown below. The field is uniformly decreasing in magnitude.       The induced current in the ring is  

Two long parallel wires are 0.30 m apart and carry currents of 5.0 A (wire 1) and 8.0 A (wire 2) in the same directions. The magnitude of the force per unit length exerted by wire 1 on wire 2 is 2.7 × 10-5 N/m. Indicate if the force is;
