4 \(\sigma_{A}=\sigma_{B}=\sigma_{C}=\sigma_{D}\)
PHXII01:ELECTRIC CHARGES AND FIELDS

358360 Consider a non-spherical conductor shown in the figure which is given a certain amount of positive charge. The charge distributes itself on the surface such that the charge densities are \(\sigma_{1}\), \(\sigma_{2}\) and \(\sigma_{3}\) at the region 1,2 and 3 respectively.

3 \(\sigma_{3}>\sigma_{1}>\sigma_{2}\)
4 \(\sigma_{2}>\sigma_{1}>\sigma_{3}\)
PHXII01:ELECTRIC CHARGES AND FIELDS

358361 Assertion :
If a point charge be rotated in a circle around a charge, the work done will be zero.
Reason :
Work done is equal to dot product of force and distance.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
