In an experiment, a boy plots a graph between (v_(max))^(2)and (a_(max))^(2) for a simple pendulum for different values of (small) amplitudes, where v_(max)and a_(max) is the maximum velocity and the maximum acceleration respectively. He found the graph to be a straight line with a negative slope, making an angle of 30^(@)when the experiment was conducted on the earth surface. When the same experiment was conducted at a height h above the surface, the line was at an angle of 60^(@). The value of h is [radius of the earth = R] |
