A stone of mass 4 kg is attached to a string of 10 m length and is whirled in a horizontal circle . Calculate the max . Velocity with which the stone can be whirled if the string can withstand a maximum tension of 160 N .

Text Solution

Verified by Experts

Here, ` m = 4 kg , r = 10 m `
` upsilon = ? T = F = 160 N `
` T = F =( mu upsilon^2)/(r) , upsilon = sqrt((Fxxr)/(m)) = sqrt((160 xx 10)/(4)) `
` = 20 m//s ` .
