Question

A boy and girl are pulling a heavy create at the same time with 7units of force each wath is the net force acts on the object is the object balance or unbalanced

Answer 1

Answer:

The question is incomplete, there are two cases, either they are pulling in same or opposite direction

Explanation:

First case is that, they are pulling in opposite direction

Taking the direction of force applied by boy is positive,

Force applied by boy = 7 units of force

Force applied by girl = -7 units of force

Net force= Force applied by boy + force applied by girl

              = 7 + (-7) units

              = 7-7 units

              = 0 units of force,

             Hence, balanced force

Second case is that, they are pulling in same direction

Taking the direction of force applied by boy is positive,

Force applied by boy = 7 units of force

Force applied by girl = 7 units of force

Net force= Force applied by boy + force applied by girl

              = 7 + 7 units

              = 14 units of force

               Hence, unbalanced force
