| Four wires, each of length 2.0 m, are bent into four loops P, Q, R and S and then suspended in a uniform magnetic field. If the same current is passed in each, then the torque will be maximum on the loop
| | | (A) P
(B) Q
(C) R
(D) S
S bcoz for a given perimeter the area of circle is maximum

Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory.

water ethanol mixture is supposed to be a non ideal mixture....
due to negative deviation from raoult's law,there is a change in enthalpy after mixing...
thus,as delta h is -ve,it is an endothermic reaction,resulting in a increase in temperature...
am i right?
