In fig 1.34 kg ball is connected by means of two mass less strings, each of length L=1.70m, to a vertical, rotating rod. The strings are tied to the rod with separation d=1.70 m and are taut. The tenion in the upper string is 35N. What are the (a) tension in the lower string, (b) magnitude of the net (b) magnitude of the net force `vecF_("net")` on the all, and (c) speed of the ball? (d) What is the direction of `vecF_("net")`?

Answer

(a) 8.74N (b) 37.9N(c) 6.45m/s (d) Leftward (radially inward)
