Awindow washer who does not want to change his position will want the forces acting on him to be
a. balanced
b. large
c. small
d. unbalanced

Before solving this question first we have to understand Newton's  first law of motion

As per Newton's first law it is impossible to change the state of rest or uniform motion along a straight line unless and until it is compelled by some external unbalanced forces.

Everybody tends to oppose the change of state of rest due to  their inertia.A book present on a table pushes the table with its weight in vertically downward direction while table applies same amount of force on the book in vertically upward direction.The net force acting on each  body is zero.So the book will show no motion.

Actually  balanced force have no role in changing the state of rest of the body. Only unbalanced force will cause the body to move.

Hence the washer who does not want to change his position will want the force acting on him to be [balanced ].

attach the statements so i can answer : )
