Spheres A and B have the same initial positive charge qo. The magnitude of the repulsive electric force between the two spheres is 14.4 N when separated by a distance of 0.03 m. (a) Find the initial charge qo. (b) The spheres are then allowed to touch each other and then separated. Find the electric force between them if the radius of sphere A is three times that of sphere B.

A proton and an electron are initially at rest at a distance of 9x10-10m. What will be their initial acceleration due to the electric force that they exert on each other?
A small sphere of charge +6x10-6C is suspended by a string of negligible mass. A charge of -9.0x10-6 C is placed directly to the right of the sphere and 0.22 m away from it. The string is deflected 5° from the vertical. Find the tension in the string.
Four-point charges (two with q = 2.5 X10-6 C and two with q = -2.50x10-6 C) are situated at the corners of a square of side 1.00 m as shown. Find the resultant force that the charge at A will experience due to the charges at the other corners of the square.
