Long back our Earth was made of molten material. Assume it to be a uniform sphere of radius R having density d. Take acceleartion due to gravity at the surface to be g and calculate the gauge pressure `(P_(0))` at the centre of this fluid Earth. Calculate `P_(0)` for following data: `R=600` km, d=5500 kg `m^(-3)` and `g=10ms^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
`P_(0)=(1)/(2)g,d,R=1.65xx10^(11)Pa`

Assuming the earth to be a homogeneous sphere of radius R , its density in terms of G (constant of gravitation) and g (acceleration due to gravity on the surface of the earth)

Assuming the earth to be a homogencous sphere of radius R. its density in terms of G (constant of gravitation) and g (acceleration due to gravity on the surface of the earth )is

If earth has uniform density, and radius 'R'. The value of acceleration due to gravity at distance d above the surface is same d below the surface. If d=((sqrtx-1)/(2))R , then find x.

The radius and mass of Earth are R and M . The acceleration due to gravity at its surface is g . Calculate the work required in raising a body of mass m to a height h from the surface of earth.

Assuming the earth to be a uniform sphere of radius 6400 km and density 5.5 g cm^(-3) , find the value of g on its surface . Given G = 6.66 xx 10^(-11) Nm^(2)kg^(-2)

If the radius of earth is R, density is rho and the acceleration due to gravity is g, then calculate the work done in raising an object of mass m through a height h from the earth's surface.

Calculate the work required to raise a body of mass m to a height h just above the earth's surface. Radius of the earth is R and acceleration due to gravity at the earth's surface is g.

Assuming the earth of to be a uniform sphere of radius 6400 kg and density 5.5 g//c.c. , find the value of g on its surface G=6.66xx10^(-11)Nm^(2)kg^(-2)
