Submit All Answers Last Answer: ffftcc Answer Incorrect, tries 1/15 Solution (i) The electric potential is zero at the center of Diagram 4. (FALSE) (ii) The electric field is zero at the center of the square in Diagram 2. (TRUE) Explanation : charges are cancel out each other. Hence, no electric field at center point (iii) You must do net positive work to move a positive charge from infinity to the origin in Diagram 3.

Solution
(i) The electric potential is zero at the center of Diagram 4. (FALSE)
(ii) The electric field is zero at the center of the square in Diagram 2. (TRUE)
Explanation : charges are cancel out each other. Hence, no electric field at center point
(iii) You must do net positive work to move a positive charge from infinity to the origin in
Diagram 3. (TRUE)
(iv) The pair of particles with masses and charges shown in diagram 1 are initially held in place
and then released.
The particle on left reaches the origin first. (FALSE)
Explanation : Both charges are at equal distance. The particle on left and the particle on right
will be reach on same speed & time.
(v) The electric field at the origin in Diagram 4 points parallel to x + y. (Cannot Tell)
(vi) The energy required to assemble the charge distribution in Diagram 4 was zero. (FALSE)
