the gauge pressure at the lower face of ...

the gauge pressure at the lower face of the block is

A

`84 Pa`

B

`384 Pa`

C

`484 Pa`

D

`784 Pa`

Text Solution

Verified by Experts

The correct Answer is:
D
`P = pressure due to to 10 cm of oil column`
+ Pressure due to `2 cm ` of water column
`=10xx0.6 g + 2 xx 1g`
`=8g = 8 xx 980 dyne cm^(-2)`
`=(8xx980)/(10) Nm^(-2) = 784 Pa`.

A highly rigid cubical block A of small mass M and slide L is fixed rigidly on to another cubical block B of the same dimensions and of low modulus of rigidity η such that the lower face of A completely covers the upper face of B. The lower face of B is rigidly held on a horizontal surface. A small force F is applied perpendicular to one of the sides faces of A. After the force is withdrawn, block A executes small oscillations the time period of which is given by.
