Look at Video Lec 15 slide #1 to answer this question. (a) Which RHR should you use to find the direction of the net magnetic field at the mid point? (b) What equation should you use to calculate the magnetic field generated by each wire? (a) RHR #1; (b)
F=qvBsin\theta
(a) RHR #1 or RHR #2 (It does not matter); (b) None of the answer choices is correct. (a) RHR #2 ; (b)
B=(\mu _(0)I)/(2R)
(a) RHR #2; (b)
B=(\mu _(0)I)/(2\pi r)
(a) RHR #2 ; (b)
\tau =NIABsin\theta
(a) RHR #1; (b)
F=ILBsin\theta
