300N
200N
140N
120N
Correct answer is D
M.A = \(\frac{E \times V.R}{100} = \frac{40 \times 6}{100} = \frac{12}{5}\)
W = M.A x effort
= \(\frac{12}{5} \times 50 = 120N\)
(sin \(\theta)^{-1}\)
\(\sin \theta\)

1.00 x 102W
3.00 x 104W
9.00 x 104W
3.00 x 105W
Correct answer is C
P = FV
= 3 x 103 x 30
= 9 x 104W
