HELLLO.......FRIEND!!
THE ANSWER IS HERE,
We know that,
Power => Force × velocity.
150watts = F1 × V1.......... (1)
Let F2 be the force , which is double the F1.
And V2 be the velocity, which is triple the V1.
P = F2×V2.......... (2)
From the question,
Divide eq (1) & (2).
150/p= (F1×V1)/(F2×V2).
150/p = (F1×V1)/(2F1×3V1)
150/p = 1/6
=> p = 150×6
=> p = 900.
:-)Hope it helps u.
