When the block is pushed, the vertical component of the push increases the normal force. Hence, there is an increase in friction.



Now when you pull the body, the vertical component of the pull is in the opposite direction of the normal reaction and hence, reduces it, thereby reducing the friction.



Hence, friction in (b) is less than friction in (a)

Pulling a body is easier than pushing
