anonymous · Answer

answer is 46mN...how??

anonymous · Answer

is 46mN true??

anonymous · Answer

Newton is force unit... what is correct answer

anonymous · Answer

yes its true...t=2iblrcos(theta)
for max torque we use t=2iblr(cos(theta)=1)
wat shall we use for calculating avg torque??

anonymous · Answer

soorry sorry its 46mN m

anonymous · Answer

its not a question from mechanics...its a question from electromagnetics

anonymous · Answer

wat are the limits of integration

anonymous · Answer

did u get 46mN m??

anonymous · Answer

in book the formula given was average torque=2IABN/pi

anonymous · Answer

i got the ans.. average torque is limit 0 to T/2 of integaration (MBsinwt dt) /(T/2)....... where M=NIBA 
the limit is 0 to T/2 as in 0 to T the total area is zero
