## At what depth below the surface of water will the pressure be equal to 1 atmosphere?

Sol: Pressure at a depth h below the surface of water = atmospheric pressure + pressure due to water column of height h. Thus a water column of height 10.2 m exerts a pressure equal to the atmospheric pressure.

## At what depth from the surface of earth the acceleration?

At what depth from the surface of the earth, the acceleration due to gravity will be (1)/(4) th the value of g on the surface of the eath ? Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. ∴d=0.75R.

## What is the height above the earth’s surface value?

⇒h=8000−6400=1600 km. So at the height of 1600 Km the value of the g becomes 64%of the g. So this is the required answer. Hence option (A) is the correct answer.

## At what height above the earth’s surface does the force of gravity decrease by 1?

Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m·s−2 per 3,200 km.)

## At what height value of g is half?

If we use 6,371 km as Earth’s radius, the distance above the surface where gravitational acceleration is halved would be 2,639 km.

## At what height above the surface of Earth the value of g is same?

Answer Expert Verified ⇒ h = 40 Km (Ans.)

## At what height above the earth’s surface the value of G becomes 36?

We can write the relation between actual acceleration due to gravity and the apparent acceleration due to gravity. Hence, the height above the surface of the earth where the acceleration due to gravity is reduced by 36% of its value on the surface of the earth is R4 . The correct option is (B).

## How much below the surface of earth does the acceleration due to gravity becomes 70?

Therefore, 1920km below the surface of earth does the acceleration due to gravity become 70% of its value at the surface of earth. Was this answer helpful?

zero

## What happens to G at the center of Earth?

At the centre of Earth, the force due to upper half of the Earth will cancel the force due to lower half. Thus, the gravitational force at the centre on any body will be 0. Since, from Newton’s law, we know F=mg. Since, mass m of an object can never be 0.

## Where is the value of G maximum and minimum on earth?

The centrifugal force for the spinning of earth is maximum at the equator and vanishes at the poles. Thus, the gravitational acceleration (g) is minimum at the equator and it is maximum at the poles.

## Where is the value of g is maximum and minimum?

Value of g is maximum at the poles, thats why we may weigh more than we are in the equators. Value of g is minimum at the equator and hence we will weigh less.
