How many milliseconds make one second?
`a) 10^3`
`b) 60`
`c) 10`
`d) 1`

Answer

A, B, C, D

Explanation

Let the bigger mass accelerates towards right with a. form the free body diagrams,
`T-ma-momega^2R=0` ……….i
`T+2ma-2momega^2R=0` …………ii
`eq. i -Eq. ii
`rarr 3ma=momega^2R`
`rarr a=(omega^2R)/3`

`Substituting the value of a in Equation i we get, `T=4/3 m omega^2R`.
