Assertion(A): A solid sphere and a hollow sphere both of same material are immersed in a liquid, then change in weight in both the spheres will be same.
Reason(R): Upthrust depends upon the volume of the solid immersed not the mass.
Reason(R): Upthrust depends upon the volume of the solid immersed not the mass.
View answer and explanation
Correct option: A
If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
Option A is correct because the Assertion is true (both spheres experience the same change in weight due to equal upthrust) and the Reason is true and correctly explains the Assertion (upthrust depends on volume immersed, not mass).

With the increase in temperature viscosity of a liquid -
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: When you squeeze one end of a tube to get toothpaste out from the other end, Pascal's principle is observed.
Reason R: A change in the pressure applied to an enclosed incompressible fluid is transmitted undiminished to every portion of the fluid and to the walls of its container.
In the light of the above statements, choose the most appropriate answer from the options given below. Hydraulic lifts and hydraulic brakes are based
on As the temperature of a liquid is raised, the coefficient of viscosity A horizontal pipe of cross-sectional diameter 5 cm carries water at velocity of . The pipe is connected to a smaller pipe with a cross-sectional diameter 4 cm. the velocity of water through the smaller pipe is If two soap bubble of different radii are connected by a tube
