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.
If hunter fires a bullet 2 degree below the horizontal
then the components of its speed is given as
so here initial speed of the bullet is not zero but have some magnitude in downwards direction
While the other bullet is dropped downwards so its initial speed will be zero
So here we can say
so if we use above equation we will find that the bullet that is shot at 2 degree below the horizontal will reach the ground first as its speed is more
