If the mass of A=10 kg, coefficient of static friction=0.22, coefficient of kinetic friction=0.2, then minimum mass of B to start motion is

A

2 kg

B

2.2 kg

C

4.8 kg

D

3.4 kg

Text Solution

Verified by Experts

The correct Answer is:
B
`mg = T = f_("max") implies mg = mu_(s) (10 g) implies m = 2.2 kg`
