Hi, Two blocks of masses 2 kg and 4 kg are connected through a massless inextensible string. The co-efficient of friction between 2 kg block and ground is 0.4 and the coefficient of friction between 4 kg block and ground is 0.6. Two forces F1 = 10 N and F2 = 20 N are applied on the blocks. Calculate the frictional force between 4 kg block and ground.How can i solve this?

Hi Aniket.
We'll start by writing equation for FBD of both of these.
