shown in the figure below is a device used to detect charge placed on a pair of small balls. Each small and very low mass ball (m=0.00163 kg) is suspended by a string of length L=0.087 meters. At the moment show in the figure, each ball carries a charge l
A small 1.45 g plastic ball that has a charge q of 1.75 C is suspended by a string that has a length L of 1.00 m in a uniform electric field, as shown in the figure. If the ball is in equilibrium when the string makes a 9.80 angle with the vertical as indicated by θ, what is the electric field strength E?
The assembly shown in the figure below consists of a thin rod of length l = 23.9 cm and mass m = 1.20 kg with a solid ball of diameter d = 10.0 cm and mass M = 2.00 kg attached to its top. The assembly is free to pivot about a frictionless axle through the bottom of the rod. The assembly is initially vertical and at rest when it starts to rotate clockwise. (a) After the combination rotates through 90...
