A ball of mass 0.1 kg. is whirled in a horizontal circle of radius 1 m. by means of a string at an initial speed of 10 rpm. Keeping the radius constant, the tension in the string is reduced to one quarter of itsinitial value. The new speed is

A ball of mass 0.1 Kg. is whirled in a horizontal circle of radius 1 m . by means of a string at an initial speed of 10 R.P.M. Keeping the radius constant, the tension in the string is reduced to one quarter of its initial value. The new speed is

An object of mass 2 kg is whirled rround in a verticle circle of radius 1m with a constant speed of 4 m//s .Then the maximum tension in the string is (g=10 m//s^(2))

An object of mass 10kg is whirled round a horizontal circle of radius 4m by a revolving string inclined 30^(@) to vertical. If the uniform speed of the object is 5 m//sec, the tension in the string (approximately) is
