ورق _____ مقدار ہے۔
- A. None of these
- B. Vector
- C. Both A and B
- D. Scalar
Correct answer
Scalar
Explanation
Explanation Work is defined as the product of force and displacement in the direction of the force: W = F ⃗ ⋅ d ⃗ = F d cos θ W = F ⋅ d = F d cos θ . The result of a dot product is a scalar (magnitude only, no direction). Thus, work is a scalar quantity.
