Explanation:
There are many students who can not get answers step by step and on time
So there are a wats up group where you can get help step by step and well explained by the trusted experts.
When force is applied on an object the object will not slide
So here object will remain in equilibrium after applying the force
So in this case the condition of equilibrium is maintained due to friction force that is applied on the object.
So here for equilibrium be can say

also we know that

we are given that
( applied force on the box)


So here this friction force on the cart is known as static friction
