54) A conical pendulum has length 100 cm and a bob of mass 100 gm is suspended from it. when the bob is set swinging in horizontal circle it makes 10 revolution in 15 sec,find a) radius of circular path b) tension in string Share with your friends Share 7 Ved Prakash Lakhera answered this The time period T=1015sWe know acceleration a=-ω2r, where r is the radius of the circular path. of S. H. M.i) So r=aω2=aT24π2=10×10×104π2×15×15=2018π2ii) Tension in the string T = mg=0.1×10=1N. -4 View Full Answer
