While writing torque, shouldn’t it be mgl/2 - (mv²• 2L)/r?

height is 2L but mv^2/r will act from COM only so at L

confused…electric field originate and terminate normally to the surface hi toh hoti hai…iska ans © diya hai… :sweat: :sweat: :sweat: :sweat:

this is only true for equipotential surfaces here there is a component parallel to the surface.

in b and d the slope of electric field lines changes ie. electric field is not uniform but infinite sheet have uniform field and since sigma + > - its field along y will be greater hence option c

Vector addition kar lo. Quadrants bana lo unko aur har quadrant ki alag se electric field likhke vector addition kar lo.

stupid logic but answer sahi aayega

@Gauri so basically we have to solve them with boolean equations?

yes… just learn the Boolean equations for two operators and if you can’t learn then try to relate them with set theory, if you can’t do that either then just know what the symbols represent and try it out yourself… make cases in rough work and you’ll figure it out… trying out options also works
