A student is swinging a ball of mass 0.323 kg in a vertical circle at constant speed, as shown in the figure below. (g indicates the direction of the acceleration due to gravity: directly downward.) The length of the string is 0.76 m. She measures the tension and finds that it is 5.601 times larger at the bottom of the circle than at the top. What is the speed of the swinging mass?

A body weighs 98 N on a spring balance at the north pole. What woill be its weight recorded on the same scale if it is shifted to the equator ? Use g = GM/R² = 98 m/s* and the radius of the earth R = 6400 km.
"Spock decides to measure the gravitational acceleration on the surface of hishome planet, Vulcan. He does so by swinging a rock at the end of a massless cord in a vertical circle. In order to complete the full circle, Spock finds that the rock needs a minimum speed of 3.0 m/s at the top of the circle. If the radius of the circle is 1.0 m, what is the gravitational acceleration on the surface of Vulcan?" Im not sure which equation to use?
