Question

A string can with stand a tension of 49newton.what is greatest speed at which a body of mass1kg can be whirled in a circle using 0.25meters length of string ​

Answer 1

Answer:

3.5ms⁻¹

Step-by-step explanation:

mv²/r=T  [For maximum tension]

Given, m=1kg, r=0.25m, t=49N, then,

v²/0.25=49

v=7ms⁻¹
