A mass `M` is suspended by a weightless string The horizontal force required to hold the mass `60^(@)` with the vertical is .

Text Solution

Verified by Experts

`F = T sin theta -----(1)`
`Mg = T cos theta -----(2)`
Dividing Eq. (1) and Eq. (2)
`(F)/(Mg) = (T sintheta)/(T costheta), F =mg tan theta`
`F =Mg tan 60^(@), F = sqrt3 Mg`
