Question

Assertion: work done by constant force is equal to magnitude of force multiplied by displacement
Reason: work done is a scalar quantity it may be positive negative or zero
A and R are true and R is the correct explanation of A
A and R are true and R is not the correct explanation of A
A is true but R is false
A and R are false
A and R are true and R is the correct explanation of A
​

Answer 1

Answer:

A and R are true and R is not the correct explanation of A

Explanation:

W=integral(F.dx)

Since F is constant, W=F.x

which is dot product of Force and displacement.

Therfore (A) is correct

Now,

W=dot peoduct of Force and displacement.

We know Dot Product always gives a scalar value.

Hence (R) is also a fact.

But R is not the correct reason for the A.
