Question

a force of 20n acts on a body if the body is 0.6m in the direction opposite to that of force calculate the work done by the force​

Answer 1

Answer:

the act of looking at something carefully, especially to see if there is anything wrong or to find the cause of a problem

Answer 2

Work done is defined as force into displacement

• Work done = FCosθ

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎=20 × 1× cos 45

( The value of cos 45° =$\frac{1}{ \sqrt{2} }$)

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎$= 20 \times \frac{1}{ \sqrt{2} }$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎$= 10 \sqrt{2} joule$
