The formula of force is

Where, F is force, m is mass of the object and a is acceleration.
A pumpkin with a mass of 2.5 kg was pushed toward a wall. The average acceleration of the pumpkin was 10.7 m/s².
Put m=2.5 and a=10.7 in the above formula.


Unit of force is N.
Therefore the force was applied to the pumpkin to make it move is 26.75 N. The correct option is 2.
