How is the weight of an object related?
Weight is the measure of the force of gravity on an object’s mass, while mass is the measure of how much matter there is in an object. An object’s weight is calculated as the mass of an object in kilograms multiplied by the acceleration of gravity exerted in meters per second squared.
What is the effect of shape of Earth on G?
Thus, acceleration due to gravity at a place is inversely proportional to the square of the distance of the point from the center of earth. Now, the earth is not perfectly spherical. It is flattened at the poles and elongated on the equatorial region is approximately 21 km more than that at the poles.
How does acceleration due to gravity change with the shape of Earth Class 9?
As the earth is an oval shape, its radius near the equator is more than its radius near poles. Since for a source mass, the acceleration due to gravity is inversely proportional to the square of the radius of the earth, it varies with latitude due to the shape of the earth.
What is the effect of non sphericity of the earth on the value of G?
The shape of the earth slightly deviates from the perfect sphere. ✞The Radius in the equatorial plane is about 21Km larger than the radius along the poles. ✞Due to this the force of gravity is more at the poles and less at the equator. ✞The value of g is accordingly larger at the poles and the less at the equator.
What is the time period of a simple pendulum at the Centre of the earth?
So time period at the centre of the earth becomes infinite. Was this answer helpful?
What is the condition for a uniform spherical mass to be a black hole?
The condition for a uniform spherical mass m of a radius r to be a black hole is [G =gravitational constant and g=acceleration due to gravity] GMc2R≥12 or √2GMR)≥e. VIT to consider JEE Main, SAT scores for engineering admissions.
What is the condition for a body to be a black hole?
Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. A black hole can be formed by the death of a massive star.
What is the dimensional formula of gravitational constant?
Or, G = [M1 L1 T-2] × [L]2 × [M]-2 = [M-1 L3 T-2]. Therefore, the gravitational constant is dimensionally represented as M-1 L3 T-2.
