Sir क्या इस सवाल को unit की सहायता से आसानी से option तक पहुंचा जा सकता है ?
So sir delta L should be final minus intial that is 8.69-8.7
Delta L is simply change in length which is determined by subtracting the smaller value from greater value of length.
@s.kumarphysicsclasses yes so it should be -ve

Good explanation! But what if we take force instead of work .. like just mgsin$ = mew mg cos theta + kx ?? Will it work ?
Energy is conserved not the force.
@@s.kumarphysicsclassesthank you for once again clearing my doubt . I realised that there is conservation of energy but there is not conservation of force law . Thank you sir !

Thanks

Good explanation 😊😊😊😊😊
Thank you sir
very nice explanation sir 😊thank you!!
Sir but in FLH rule middle finger represents current direction naa then how come velocity direction is taken??pls respond
This rule is used to determine the direction of force acting on: (i) a charged particle moving perpendicular to a magnetic field (ii) a current carrying conductor held perpendicular to a magnetic field. If we stretch the first finger, central finger and the thumb of our left hand mutually perpendicular to each other such that the first finger is in the direction of magnetic field, central finger is in the direction of velocity of positive charged particle (or electric current flowing in a conductor) then the thumb will represent the direction of force acting on the particle (or conductor).
great explanation
Good explanation ❤
Thanks you sir 👍👍👍
Nice explanation
Very very very thank you so much sir really ❤❤❤❤❤
