A particle of mass 100 g is moving in a ...

A particle of mass 100 g is moving in a vertical circle of radius 2 m The particle is just looping the loop . What is the speed of the particle and tension in the string at the highest point of the circular path ? . `(g =10 ms^(-2))` .

Text Solution

Verified by Experts

Here, ` m = 100 g = 0.1 kg, r= 2 m `
` upsilon _(H) = ? , T_(H) = ? `
When the particle is just looping the loop ` upsilon _(H) sqrt(g r) = sqrt(10 xx 2) = 4.47 ms^(-1)`
At the highest point ` T_(H) = Zero ` .
