The coefficient of static friction, mu(s...

The coefficient of static friction, `mu_(s)` between block A of mass 2 kg and the table as shown in the figure is 0.2. What would be the maximum mass value of block B so that the two blocks do not move? The string and the pulley are assumed to be smooth and massless.`(g=10m//s^(2))`

A

4.0kg.

B

0.2kg.

C

0.4kg.

D

2.0kg.

Text Solution

Verified by Experts

The correct Answer is:
C

`T=M_(B)g=mu_(s)M_(A)g`
`therefore M_(B)=mu_(s)M_(A)=0.2xx2=0.4kg`
