Answer:
The correct answer is (D) V=a
Explanation:
Gravitational potential strength is the energy possessed or received with the aid of an item because of a alternate in its role while it's far present in a gravitational subject. In simple terms, it may be said that gravitational capacity strength is an energy this is related to gravitational force or to gravity.
The most not unusual instance that assist you to apprehend the concept of gravitational ability strength is in case you take pencils. One is placed at the desk and the other is held above the desk. Now, we are able to nation that the pencil that's excessive can have greater gravitational capacity strength than the pencil that is at the desk.
whilst a frame of mass (m) is moved from infinity to a degree in the gravitational influence of a supply mass (M) without accelerating it, the quantity of labor done in displacing it into the supply subject is saved in the form of capacity electricity. this is known as gravitational capacity electricity. it's far represented with the image Ug.
rationalization: We recognize that the ability power of a frame at a given position is defined because the power saved within the frame at that position. If the location of the body modifications because of the application of external forces the change in ability electricity is identical to the quantity of labor performed at the frame by the forces.
beneath the motion of gravitational pressure, the paintings done is impartial of the course taken for a alternate in position so the pressure is a conservative pressure. except, all such forces have some capacity in them.
The gravitational impact on a frame at infinity is 0, consequently, capability electricity is 0, which is referred to as a reference factor.
