The bob of a single pendulum has a mass of 0.02kg. Determine the weight of the bob [g = 10ms-2]
0.02N
0.20N
20.00N
200.00N
Correct answer is B
Wt = mg = 0.02 x 10 = 0.2N
140.0N
20.0N
4.0N
0.8N
Correct answer is B
F = \(\frac{mv - mu}{t} = \frac{16 - 12}{0.2} = 20N\)
240N
96N
20N
9N
Correct answer is B
F = ma = \(\frac{mv}{t} = \frac{8 \times 30}{2.5} = 96\)
