A flat car is given an acceleration a(0)...

A flat car is given an acceleration `a_(0)=2m//s^(2)` starting from rest. A cable is connected to a crate of weight `50kg` as shown whose other end is attached to a fixed support on ground. Neglect friction between the floor and the car wheels and also the mass of the pulley. Calcuollate corresponding tension in th cable if `mu=0.30` between the crate and the floor or the car.

A

`350N`

B

`250N`

C

`300N`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
Acceleration of crate will be `2a_(0)` .
`T-f_(k)=m(2a_(0)` implies `T-mumg=2ma_(0)`
`T-0.3xx50xx10=2xx50xx2` implies `T=350N` .
