A negative charge, if free, will tend to move from high potential to low potenti

Question

A negative charge, if free, will tend to move from high potential to low potential. from low potential to high potential. toward infinity. away from infinity. in the direction of the electric field. Suppose you have two point charges of opposite sign. As you move them farther and farther apart, the potential energy of this system relative to infinity increases. decreases. stays the same. Suppose a region of space has a uniform electric field, directed towards the right, as shown in the figure. Which statement about the electric potential is true? The potential at all three locations (A, B, C) is the same because the field is uniform. The potential at points A and B are equal, and the potential at point C is higher than the potential at point A. The potential at points A and B are equal, and the potential at point C is lower than the potential at point A. The potential at point A is the highest, the potential at point B is the second highest, and the potential at point C is the lowest. When the electric field is zero at a point, the potential must also be zero there. True False

Explanation / Answer

4)

as the negative charge moves in the direction of oposite of electric field.

electric potential decreases in the direction of electric field

hence , the negative charge will move B) from low potential to higher potential

5)

as the energy will be negative initially ,

when move away , the potential energy os system will A) increases

6)

electric potential decreases in the direction of electric field.

as the point A and B lies in the same equipotential surface , potential at A and B is same

and potential at C is lower than A and B

the correct option is C)

7)

False

this is not true

at the centre of square with four equal charges at corners ,

electric field is zero but electric potential is non zero
