A conducting ring of radius a is rotated about a point O on its periphery as shown in the figure in a plane perpendicular to uniform magnetic field B which exists everywhere. The rotational velocity is omega. Choose the correct statement(s) related to the potential of the points P, Q and R |

Answer» `V_(P)-V_(O)GT0 and V_(R)-V_(O)LT0` `V_(P)-V_(O)=V_(R)-V_(O)=Bomegaa^(2)` `V_(P)=V_(R) gt V_(O)` `V_(Q)-V_(P)=(V_(Q)-V_(P))-(V_(P)-V_(O))` `=1/2Bomega(2a)^(2)-(1/2Bomega(sqrt(2)a)^(2))=Bomegaa^(2)` `=V_(Q)-V_(P)=V_(P)-V_(Q)` |
