Question

A body. constrained to move in the Y-
direction is subjected to a force given by
F=2i +15j +6k) N. What is the work done
by this force in moving the body a distance
10 m along the Y-axis
(a) 20 J (b) 150 J (c) 160 J (d) 190 J​

Answer 1

Answer:

b) 150J

Explanation:

Force, F = 2i + 15j + 6k

j is the direction of Y-axis

displacement in Y direction = 10m

So Force, F in Y direction = 15×10 = 150J
