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