#### Question

A stone of mass 1 kg is whirled in horizontal circle attached at the end of a 1 m long string. If the string makes an angle of 30^{º} with vertical, calculate the centripetal force acting on the stone.(g=9.8m/s^{2}).

#### Solution

m = 1kg

`Tcos30^@= mg`

`T=(mg)/(cos30^@)`

`F_c = Tsin30^@`

`F_c=(mg)/cos30^@""xxsin30^@`

=mg × tan30º

= 1 × 9.8 × 1/√3

= 9.8/1.732

=5.658N

the centripetal force acting on the stone is 5.658N

Is there an error in this question or solution?
