1) Out of the page t) Into the page 11 To the righ IV)To the let As shown in the diagram beow, a lone straight wise carrying 5.0 A currem tobe xiat is pased do ema current loop carrying the same currens of 3.0 A shockwiss The of the circular loop is 20 cm. The direction of the net magnetic held at the censer of the circular loop at Pis (i) Into the page (ii) Out of the page il) To the left v) To the right (k) A metal bar travels in a uniform magnetic field as shown below. Where do the induced positive charges accumulate on this bar? eft (ii) Right (ii) Top (iv) Bottom (v) No induced c Page 6 of 13Explanation / Answer
Q1 = out of the page
bcz upper wire has B into the page and lower wire has B out of the page but point P is near lower wire so its B will be grater than upper wire B so net B will bw out of the page,
Q2
Bnet = Bwire - B loop = ui / 2*pi*r - u*i /2R = u*i *( 1/ 3.14 *0.4 - 1/ 0.4 ) < 0
so field will be inot the page here loop B field dominant over wire B field
