The angular velocity of the earth will be

Options

A. `(2pi)/86400 rad S^(-1)`
B. `(pi)/86400 rad S^(-1)`
C. `(2pi)/43200 rad S^(-1)`
D. `(pi)/(43200) "rad" s^(-1)`

Answer

A

Explanation

for earth ,T `=24hrArr=24xx60xx60=86400s`
`therefore` Angular velocity of the earth
`omega =(2pi)/T=(2pi)/86400rad s^(-1)`
