A smooth wedge of mass M is pushed with ...


A smooth wedge of mass M is pushed with an acceleration `a=gtantheta` and a block of mass m is projected down the slant with a velocity v relative to the wedge.
Q. The normal reaction between wedge and block is:

A

`mgcostheta`

B

`mgsectheta`

C

`mgcottheta`

D

`mgtantheta`

Text Solution

Verified by Experts

The correct Answer is:
B
Normal reaction `N_R=mgcostheta+masintheta`
`N_R=mgcostheta+mg(sin^2theta)/(costheta)=mgsectheta`
