A bike of mass 200 kg (with rider) is running on the road with constant speed `5 m//s`, the reaction exerted on the bike by the road at the lowest point will be (`g= 10 m//s^(2)`)

Options

A. 200 N
B. 2050 N
C. 1950 N
D. None of these

Answer

B

Explanation

FBD bike with rider

`R-200g=(200v^(2))/(R )=(200xx25)/(100)`
`R=200g+50`
`R=2050N`
