An object with mass 30kg and specific gravity 3.6 is placed in a fluid whose specific gravity is 1.2. Neglecting viscosity, which of the following is true?
A. The acceleration of the object is (1/3)g and its apparent weight is 100N.
B. The acceleration of the object is (2/3)g and its apparent weight is 100N.
C. The acceleration of the object is (1/3)g and its apparent weight is 200N.
D. The acceleration of the object is (2/3)g and its apparent weight is 200N.
Equations I used:
g can be rounded to 10
[tex]\rho[/tex]=m/v
F=mg=[tex]\rho[/tex]Vg
I know the volume does not change. I know the answer is D but I don't know why.. When I attempted to solve it I attempted to do a proportion and I keep getting an apparent weight of 100N. Please explain why it is D.
