Oct 29, 2020 at 13:11 comment added Bhavay In absence of gravity , there is no friction btw the blocks, as there will be no normal forces btw the blocks.
Oct 29, 2020 at 13:02 comment added Modulus @Bhavay an external force. Situation 2 is located in a vacuum with no gravity and no ground. (But there is an external Force Fn making Frmax > 0)
Oct 29, 2020 at 12:39 comment added Bhavay What is $F_2$? is it the friction force by the ground on block b or an external force ?
