Question

Choose the correct one-
 A block of ice floats in water, such that the temperature of ice as well as water is 0 degree C. In this situation, the wt. of ice =
(a)Wt. of water displaced by the immersed part of ice
(b) Volume of water displaced by the immersed part of ice
(c)Wt. of water displ. by the complete block of ice
(d) None
Please explain as well

Answer 1

Weight of ice equals Wt. of water displaced by the immersed part of ice

This is from the statement of archimedes principle - The upward force experienced by a body in a liquid is equal to the weight of liquid displaced by the immersed part of the body.
When the ice block floats in water i.e. the forces on the bock of ice are balanced, upward force (also called buoyant force) is equal to the weight of the ice (from its free body diagram).

Answer 2

answer is

(a) Weight of ice equals Wt. of water displaced by the immersed part of ice

This as as per the Archimedes principle: The upward force experienced by a body in a liquid is equal to the weight of liquid displaced by the immersed part of the body.

As the ice block floats in water, upward force is equal to the weight of the ice.
