Question
Following are some statements about buoyant force: (Liquid is of uniform density)
(i) Buoyant force depends upon orientation of the concerned body inside the liquid.
(ii) Buoyant force depends upon the density of the body immersed.
(iii) Buoyant force depends on the fact whether the system is on moon or on the earth.
(iv) Buoyant force depends upon the depth at which the body (fully immersed in the liquid) is placed inside the liquid.
Of these statements :
(i) Buoyant force depends upon orientation of the concerned body inside the liquid.
(ii) Buoyant force depends upon the density of the body immersed.
(iii) Buoyant force depends on the fact whether the system is on moon or on the earth.
(iv) Buoyant force depends upon the depth at which the body (fully immersed in the liquid) is placed inside the liquid.
Of these statements :
Options
A.Only (i), (ii) and (iv) are correct.
B.Only (ii) is correct.
C.Only (iii) and (iv) are correct.
D.(i), (ii) and (iv) are incorrect.
Solution
(C or D)
Fb = vρliqg
′g′ is different on moon and on the earth.
Hence only (iii) is a correct statement.
Fb = vρliqg
′g′ is different on moon and on the earth.
Hence only (iii) is a correct statement.
