1.	A bob of mass 3 kg is attached with a light string of length R. If it is given an initial velocity u=√9gR at the bottom most point, the tension in the string at the topmost point is (Take g=10 m/s2)
Answer» A bob of mass $3 kg$ is attached with a light string of length $R$ . If it is given an initial velocity $u = \sqrt{9 g R}$ at the bottom most point, the tension in the string at the topmost point is (Take $g = 10 {m/s}^{2}$ )
