The force F exerted by an electric field on a test charge q is given by:
From this equation we notice that if we change the test charge then the force will change as well.
Therefore, the forces on the charges will not be the same.
We can't determine the electric field without further information on the problem; we need the force on one of the test charges to determine the magnitude of the field.
Answer:
Real images are formed where rays of light actually converge, whereas virtual images occur with they are perceived to converge. Real images can be produced by passing light through converging lenses or with a concave mirror of some sort.

The combined amount of kinetic and potential energy of its molecules
Answer:
G=GM/r^2
G=(6.67×10^-11)(6.39×10^23)/(3390000+400000)^2
G=(6.67×10^-11)(6.39×10^23)/(3790000)^2
G=2.967 m/s^2

Answer:
Explanation:
As we know that here final equilibrium temperature is 0 degree C
so we can use energy conservation here
heat given by the cube = heat absorbed by the ice
so we have
so here we have
