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
Answers
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
