Question

12) Find the work. If a 220N force apply on the body at 60° from Horizontal. If the
displacement is horizontal direction is 10m.​

Answer 1

$\huge\mathfrak\red{ANSWER}$

1100J

Explanation:

WORK IS SAID TO BE DONE WHEN A FORCE IS APPLIED ON A BODY AND THAT BODY UNDERGOES DISPLACEMENT.

S.I UNIT OF WORK IS JOULE.

WORK IS ALSO THE PRODUCT OF FORCE AND DISPLACEMENT.

AND FOR HORIZONTAL ANGLES WORK IS PRODUCT OF FORCE, DISPLACEMENT AND COS 60°.

______________________________________

COMING TO THE QUESTION. -->>

IT IS GIVEN :

FORCE APPLIED ON BODY = 220N

DISPLACEMENT OF BODY = 10M

WORK DONE =?

NOW, FOR A BODY ON WHICH SOME WORK IS DONE ON HORIZONTAL ANGLE

WORK = FORCE × DISPLACEMENT × COS 60°

IN THIS CASE:

WORK DONE = 220 × 10 × COS 60°

SINCE COS 60° IS 1/2

THEREFORE WE GET - WORK DONE ON BODY

$= 220 \times 10 \div 2$

$= 1100joule$

THUS WORK DONE ON BODY IS 1100 JOULE.
