A solid plastic cube of side 0.2m is submerged in a liquid density of 0.8kg\(m^{-3}\). Calculate the upthrust of the liquid on the cube (g=10\(ms^{-2}\)
A
0.064N
B
0.025N
C
0.016N
D
0.008N
E
0.003N
Verified Correct Answer: A.
Physical Principles & Numerical Solution
Upthrust = Volume of fluid displaced =vpg =0.2 x 0.2 x 0.2 x0.8 x 10= 0.064N
