A charge q is kept at centre of circle of radius r .If permitvity of f

1.	A charge q is kept at centre of circle of radius r .If permitvity of free space is e0 then the work done in carrying a charge q along the diameter of circle will be
Answer» FINAL Answer : 0 Understanding : 1) We observe the motion of charge as shown in pic . 2) As we see, we get that Force is perpendicular to DIRECTION of displacement. 3) Hence, There is no contribution of WORK by the force on motion of this charge particle . For Mathematical proof, see pic

FINAL Answer : 0

Understanding :

1) We observe the motion of charge as shown in pic .

2) As we see, we get that Force is perpendicular to DIRECTION of displacement.

3) Hence, There is no contribution of WORK by the force on motion of this charge particle .

For Mathematical proof, see pic
