The minimum acceleration that must be impprted to the cart in the figure so that the block `A` will not fall (given `mu` is the coefficient if friction between the surface of block and cart) is given by:

A

`mug`

B

`mu//g`

C

`g//mu`

D

none

Text Solution

Verified by Experts

The correct Answer is:
C
Solving from the frame of cart, we get
`N=ma, mg =mu N rArr mg =mu ma`
`rArr a=g/(mu)`
