Question

8.
When a force (8i+41) newton displaces a
particle through (31-3Ì metre, the power is
0.6 W. The time of action of the force is​

Answer 1

Answer:

Explanation:

20 s

f.s/t=W

Answer 2

Answer:As you know that

Power = Work done/Time Taken

Now, Work done = F•d

So, W = 12J

Now 12/t = 0.6

=> t = 20s
