(Solved): When a uniform electric field of E=(3.105i+5.105j)N/C is applied to a cork ball with a mass of ...
When a uniform electric field of is applied to a cork ball with a mass of suspended from the ceiling by a very thin string, the string remains in balance by making an angle of with the vertical. What is the charge of the ball? (Express your answer in the unit of micro-Coulomb)
Expert Answer
This is a problem related to electrostatics. The force on the cork ball due to the electric field is given by: where F is the force, q is the charge on the cork ball, and E is the electric field.here magnitude of E can be obtained as In this proble...
