Question

The angles between the force and the displacement for maximum and minimum work respectively be
(1) 90° and 0°
(3) 0° and 180°
(2) 0° and 90°
(4) 180° and 0°​

Answer 1

Answer:

2)maximum is 0degree

minimum is 90degree

Answer 2

$\large{\underline{\mathscr{Explanation}}}$

__________________________

Work Done=Force x Displacement x Cos$\theta$

Here,

Maximum Value of $\theta$ will be at 0°=>1

Minimum Value of $\theta$ will be at 180°=> -1

Therefore Option 2 is correct.
