TheGravitational field is the space around the planet up to where the effect of gravity can be felt.
It is the force experienced by a unit mass of an object, within the gravitational field. Its SI unit is N/kg
The gravitational field intensity is calculated by using following formula:
If the object is on the surface I =
If the object is at height H =
If the object is at certain distance d =
They are the points which border the space with the gravitational field.Neutral points are those points in the space at where the gravitational field intensity is zero.The artificial satellites which have launched from the earth generally revolve around the neutral points.
The space around a planet where the gravity of the planet has its influence on an object is gravitational field.
The gravitational field depends on the mass of the planet.
The gravitational field intensity of the planet or a satellite is defined as the gravity that applies to an object of unit mass at a point within its gravitational field.
Gravitational field intensity is measured in N/Kg unit.
The gravitational field intensity of the earth = E1
The gravitational field intensity of the earth when it is squeezed to the size of the moon = E2
Radius of the earth (R1)= 63.8 × 105 m
Radius of the moon (R2)= 1.7 × 106 m
We have, \
or,E2 = 14.08 E1
Thus, the gravitational field intensity of the earth will increase by about 14 times, if it is squeezed to the size of the moon.
The space around a planet where the gravity of the planet has its influence on an object is the gravitational field.
The gravitational field intensity at a point in a gravitational field is defined as force experienced by unit mass placed at that point.
Which of the following formula is correct to calculate gravitational field intensity?
______ are the points which border the space with gravitational field
Gravitational field intensity
All of above
Gravitional field is defined as _______.
The point experienced in a feely falling body due to the force of gravity.
The space around a mass over which it can exert gravitational force on other masses.
The space aound object over which it can experience gravity.
The point experienced by unit mass placed at that point.
