A body weighing 14N in air is partially immersed in water. If the mass of water displaced in the process is 200g, calculate the upthrust on the body. [g=10(m/s^{2})]
-
A.
2.0N -
B.
3.0N -
C.
3.5N -
D.
7.0N
Correct Answer: Option A
Explanation
Upthrust = weight of liquid displaced
= mass of liquid displaced (times) acceleration due to gravity
= (frac{200}{1000} times 10)
= 2N
