Two moving objects have the same momentum. Object 1 has three times the mass of Object 2; therefore, Object 1 has: the same the velocity of Object 2
three times the velocity of Object 2
nine times the velocity of Object 2
one-third the velocity of Object 2
one-ninth the velocity of Object 2

Asmall 12.00g plastic ball is suspended by a string in a uniform, horizontal electric field with a magnitude of 10^3 n/c. if the ball is in equilibrium when the string makes a 30 ° angle with the vertical, what is the net charge on the ball?
