A smooth table is placed horizontally and an ideal spring of spring constant k = 1000 N/m and unextended length of 0.5 has one end fixed to its centre. The other end is attached to a mass of 5 kg which is moving in a circle with constant speed 20 m/s. then the tension in the spring and the extension of this spring beyond its normal length are-
- 1200 N, 1.2, m
- 600 N, 0.6, m
- 700 N, 0.7, m
- 800 N, 0.8 m
Answer
(A) 1200 N, 1.2, m
