In which of the following situations or place would you want to reduce the force of friction ( multiple answers) a.) moving your mouse along the mousepad b.) the axle of your car wheels while you are driving c.) you are climbing a steep ladder d.) the surface of a park bench while you sitting on it

here friction must be reduced when

B.) the axle of your car wheels while you are driving

Explanation:

Friction is a type of force which is required in many process and in those if we reduce the friction then the system may not work

So here we know that

A.) moving your mouse along the mousepad

Here we know that the mousepad is working when mouse runs on the pad and if it makes frictionless than it will not work

B.) the axle of your car wheels while you are driving

Here we must have to reduce the friction because here if motion of axle is smooth then it will have less energy loss

C.) you are climbing a steep ladder

While climbing on the steep ladder we must require large friction for balancing

D.) the surface of a park bench while you sitting on it

While sitting on the bench we require friction for our static equilibrium

so here friction must be reduced when

B.) the axle of your car wheels while you are driving
