Ravi applied a force of 10 N and moved a book 30 cm in the direction of the force. How much was the work done by Ravi?
उत्तर
Given,
Force (F) = 10 N,
Displacement (s) = 30 सेमी
= 30 × 10-2 मी
Find: Work done (W)
Formula: W = F × s
Calculations:
W = 10 × 30 × 10-2
W = `(10 xx 30)/100`
W = 3 J
work done by Ravi is 3 J.
