Question

A weightless thread can withstand tension upto 30 n. a stone of mass 0.5 kg is tied to it and is revolved in a circular path of radius 2m in a vertical plane. if g = 10 m/s2 , then the maximum angular velocity of the stone can be :–

Answer 1

hey friend!!

______
your answer is "5 rad/s"

Explaination:=>

we know that.

T(max) = mw2(max)r + mg

T(max)/m = w2(max)×r + g

30/.5 = w2(max)×r + 10

60-10 = w2(max)×r

w2(max) = 50/r

w2(max) = 50/2 = 25

then

W(max) = 5 rad/s________answer


hope it will help you..
