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
Correct Answer: A. 0.064N
Explanation
Upthrust = Volume of fluid displaced =vpg =0.2 x 0.2 x 0.2 x0.8 x 10= 0.064N
