Answered by akankshaprjpt

because to open a door torque must be applied and as the distance is 0 it can't be opened.

hope this is what you want , if you like this plss mark as the brainliest!

qais: yup...now u are right

qais: simple words...torque = force x perpendicular distance from the axis of rotation
here distance is zero so torque is zero

qais: yes poojan i know that
but im sad because moderator works very slow here

qais: it's ok
at least u corrected this :)

HLO MATE HERE U GO

⭐. TORQUE = FORCE × Lever arm of the force

when the force is applied at hings , lever arm of the force will be zero .

⭐. so there will be no torque and hence we cannot open or close the door.
