Question

which one is scalar product?
1.work
2.mass
3.density
4.torque

Answer 1

Work is scalar product of Displacement and Force .
Here is the equation \[W = F \times S \cos \theta \]

Answer 2

work

Answer 3

what u did @devarsh.ruparelia??

Answer 4

dot product is scalar product so none is a scalar product

Answer 5

scalar product doesn't mean that product of 2 scalars but multiplication of 2 vectors
but product gives u scalar
work is a vector so it is not scalar product
mass as it is not a product of 2 vectors it is not scalar product
same with density
at last it is torque is a vector so it is not scalar product

Answer 6

@kr7210 What I did was dot product of 2 vectors which results in the scalar quantity.
