60g
80g
120g
200g
Correct answer is D
Clock-wise moment = Anti-clock wise
Hence 120 × (35−10)= Xg ×(50−35)
120 × 25 = Xg × 15
Xg = 200g
4.2ms-1
4.7ms-1
5.6ms-1
7.1ms-1
Correct answer is B
R = Ucos\(\theta\) x t
U = \(\frac{R}{Cos \theta \times t}\)
= \(\frac{4.50}{Cos40N.25}\)
= 4.699m/s
0.5ms-2
2.0ms-2
10.0ms-2
40.0ms-2
Correct answer is B
Slope = a = \(\frac{\deltav}{\deltat}\)
= \(\frac{50 - 10}{30 - 10}\)
= 2.0ms-2
4J
15J
5J
100J
Correct answer is D
W = FS = 20 X 5
= 100J
1200g
1000g
800g
400g
Correct answer is C
Mass = density x volume
400 x 2.5 = 1000g
Loss in mass = volume x density
= \(\frac{400}{2}\) x 1 = 200g
Reading on spring balance = 1000 - 200g = 800g
