Question

Consider the following statements:
A. The pressure increases as the depth increase.
B. Upthrust on a body depends on the acceleration due to gravity, the density of the liquid and the volume of the body immersed in the liquid.
Which of the following option is true?

• A. Both `A’ and `B’ are true statements
• B. ‘A’ is true but ‘B’ is false
• C. ‘A’ is false but ‘B’ is true
• D. Both ‘A’ and ‘B’ are false

Answer 1

The correct option is A

Both `A’ and `B’ are true statements

Both A and B are true statements.
A: As the depth increases the weight of the column above it increases thus the pressure increases.

B: When a body is immersed fully or partially in a fluid, it experiences an upward force that is equal to the weight of the fluid displaced by it.
Upthrust = Volume of body $\times$ density of liquid $\times$ acceleration due to gravity.
