8.9 x 10-3m3
6.4 x 10-3m3
3.2 x 10-3m3
3.0 x 10-3m3
Correct answer is B
Upthrust = 96 - 32 = 64N
mass(m) = \(\frac{64}{10} = 6.4 kg\)
volume = \(\frac{mass}{Density} = \frac{6.4}{1000}\)
= 6.4 x 10-3m3
Which of the following statements about pressure is not correct? pressure
increases with an increase in surface area
decreases with an increase in surface area

20N
10N
6N
4N
Correct answer is C
Upthrust = Weight of fluid displayed = 6N
24.0N
12.5N
7.5N
4.0N
Correct answer is B
F = ma
= 1 x 2.5 = 2.5N
weight = mg = 1 x 10 = 10N
Reading = F + Wt = 2.5 + 10
= 12.5N
