Your answer should be:
Acceleration
Answer:
1) The net electric field at any location inside a block of copper is zero if the copper block is in equilibrium.
2) In equilibrium, there is no net flow of mobile charged particles inside a conductor.
3) If the net electric field at a particular location inside a piece of metal is not zero, the metal is not in equilibrium.
Explanation:
1) and 3) A block of copper is a conductor. The charged particles on a conductor in equilibrium are at rest, so the intensity of the electric field at all interior points of the conductor is zero, otherwise, the charges would move resulting in an electric current.
2) The charged particles on a conductor in equilibrium are at rest.
Explanation:
The gravitational force between two masses having masses. Let m is the mass of smaller object and M is the mass of larger object. The gravitational force between these two spheres is given by :
r is the separation between two spheres
G is universal gravitational constant,
The value of G remains same always no matter how objects are placed.
