Test Academy | A smooth table is placed horizontally and an ideal spring of spring constant k = 1000 N / m and unextended length of 0.5m has one end fixed to its centre. The other end is attached to a mass of 5kg which is moving in a circle with constant speed 20m /s . Then the tension in the spring and the extension of this spring beyond its normal length are 500 N, 0.5 m, 600 N, 0.6 m, 700 N, 0.7 m, 800 N, 0.8 m
