A satellite small enough to be treated as a point particle. Can earth's gravity exert a torque on a satellite about the earth's center?
Torque causes an object to rotate around a specific point.
Torque = force * perpendicular distance
and
Torque = moment of Inertia * angular acceleration.
When a satellite is launched, it is forced up to a specific distance from the earth's center and accelerated to a specific velocity parallel to the surface of the earth. The satellite continues moving in circular orbit.
The force which causes the satellite to move in a circular path is the gravitational force caused by the mass of the earth, mass of the satellite, and distance from the center of mass of the earth to the center of mass of the satellite. This force causes the direction of the velocity to rotate so it is always tangent to the circle.
This force produces the torque which makes causes the satellite to rotate so the direction of its velocity is always perpendicular to the direction of the gravitational force.

How does gravity affect a satellite launch?
Gravity affects a satellite launch by pulling the satellite towards the Earth during its initial phase of ascent. This requires the rocket to generate enough thrust to overcome gravity in order to reach the desired orbit. Once the satellite is in orbit, gravity continues to affect its trajectory, helping to keep it in orbit around the Earth.
What happens to the size of the centripetal force due to gravity acting on the satellite if the satellite moves farther from earth?
The centripetal force due to gravity decreases as the satellite moves farther from Earth because the force of gravity weakens with distance. This is in accordance with the inverse square law, which states that the force of gravity decreases with the square of the distance between two objects.
Where is the acceleration of satellite directed?
The acceleration of a satellite is generally directed towards the center of the celestial body it is orbiting, such as the Earth for a satellite in Earth's orbit. This acceleration is due to gravity, which keeps the satellite in its orbit.
Why is the moon known as the a satellite?
Assuming no typo on your part regarding the "A" satellite, it would be that the moon was the first satellite orbiting earth. If you meant "why is the moon known as a satellite", it's because it is a satellite. Anything that orbits is a satellite.
What is the torque due to gravity on the disk?
The torque due to gravity on the disk is the force of gravity multiplied by the distance from the center of the disk to where the force is applied.

How gravity is produced in satellite?
Gravity is not artificially produced in satellites.Whatever (negligible) gravity they have is due to their own mass.
Does satellite has acceleration due to gravity or not?
yes, this ADG helps the satellite to orbit earth. This is the centripital force

How torque is developed due to alignment of two fields?
Torque is developed by, among other things as well, the magnetic attraction or repulsion of two magnetic fields, contributing through rotational leverage to produce a net torque.
If a satellite is travelling in orbit around the earth and the gravitational force drops to nil what will happen to the satellite?
Without gravity, the satellite will travel in the same direction it was going when gravity went to nil. This is due to the object's momentum, and the satellite will go off into space. And if the gravitation were nil to begin with, there would have been no orbit in the first place. The question is problematic, since planets will always have gravity. Picture a ball on a string that is being whirled around by someone. If the string snaps, the ball continues to move in the direction it was going at the moment the string snapped. It flies off in a tangent, and the satellite will do the same thing if gravity is suddenly reduced to zero.
When do objects tip over resulting from the torque due to gravity?
Objects tip over when the center of gravity is not directly above the base of support, causing a torque that exceeds the object's stability limit. This tipping point typically occurs when the center of gravity passes outside the object's base of support. Height and weight distribution can also influence an object's tipping over.
What is meant by moment coefficient about Centre of Gravity?
The moment coefficient about the center of gravity is a measure of an object's tendency to rotate due to an applied force. It is calculated by multiplying the force by the perpendicular distance from the center of gravity. It quantifies the torque or rotational force acting on an object.
