Correct Option: B
When a pail of water is swung in a vertical circle, the water does not fall out at the top of the loop when the speed is great enough. At every point in the circle the water tries to fall vertically out due to the force of gravity g but also tries to move in a straight line due to its circular motion. If the velocity is large enough the water will not drop out of the bucket far enough before it is moved round the circle. The value of g does not depend upon the object’s mass.
