Question

The work done by a variable force is calculated using the formula:

विकल्प

• W = F × s

• W = ∫F·ds between limits

• W = F·s·cos θ

• W = (F₁ + F₂)/2 × s

Answer 1

W = ∫F·ds between limits

Explanation:

Integration sums up all the tiny work elements (dW = F·ds) from start to end position.
