A3.00-kg ball swings rapidly in a complete vertical circle of radius 2.00 m by a light string that is fixed at one end. the ball moves so fast that the string is always taut and perpendicular to the velocity of the ball. as the ball swings from its lowest point to its highest point
a/ the work done on it by gravity is +118 j and the work done on it by the tension in the string is -118 j.
b/the work done on it by gravity is -118 j and the work done on it by the tension in the string is zero.
c/the work done on it by gravity and the work done on it by the tension in the string are both equal to zero.
d/ the work done on it by gravity and the work done on it by the tension in the string are both equal to -118 j.
e/ the work done on it by gravity is -118 j and the work done on it by the tension in the string is +118 j.
