Questions
Find the value of friction forces between the blocks A and B; and between B and ground. (Take, g=10 )
detailed solution
Correct option is D
Maximum force of friction between ground and B is fmax=(M+m)μg=(15+5)(0.6)(10)=120 NAs fmax>F∴ Frictional force between B and ground will be 80 Nand that between A and B is zero.Talk to our academic expert!
