An isosceles right angled current carrying loop PQR is placed in a uniform magnetic field vecB pointing along PR. If the magnetic force acting on the arm PQ is F, then the magnetic force which acts on the arm QR will be |
|
Answer» `F` [Hint : Net force on entire loop PQR is zero and force on area RP is ALSO zero because here current is ANTIPARALLEL to magnetic field B. `rArrF_(PQ)+F_(QR)=0` or `F_(QR)=-F_(PQ)=-F`] |
