Question

Two blocks A and B with masses 60 kg and 50 kg respectively are connected through an ideal string and placed on a rough horizontal surface with coefficient of friction mu=0.2 horizontal forces are applied on blocks the friction force acting on B will be

Answer 1

mu=0.2

a=60. b=50

$60 \div 50$

=1.2

$= 1.2 \times 0.2$

0.24
