📘Question

A force F = α+βx^2 acts on an object in thex-direction. The work done by the force is 5J when the object is displaced by 1 m. If the constant α = 1N then β will be

(1) 15 N/m^

(2) 10 N/m^2

(3) 12 N/m^2

(4) 8 N/m^2                 (JEE-2025) 

✅ Answer

Ans. (3)

A force F = α+βx^2 acts on an object in thex-direction. The work done by the force is 5J when the object is displaced by 1 m. If the constant α = 1N then β will be (1) 15 N/m^ (2) 10 N/m^2 (3) 12 N/m^2 (4) 8 N/m^2
