Statement I: no electric current will be present within a region having uniform and constant magetic field. Statement II: Within a region of unifrom and cinstant magnetic field vec(B) , the path integral of magnetic field oint vec(B).dvec(l) along any closed path is zero. Hence, from Ampere cirauital law oint vec(B).dvec(l) = mu_(0)I (where the given terms ahve usual meaning), no current can be present within a region having uniform and constant magnetic field .

A: In any magnetic field region the line integral ointvecB.vec(dl) along a closed loop is always zero. R: The magnetic field vecB in the expressioin oint vecB.vec(dl) is due to the currents enclosed only by the loop.

A closed current-carrying loop having a current I is having area A. Magnetic moment of this loop is defined as vec(mu) = vec(IA) where direction of area vector is towards the observer if current is flowing in anticlockwise direction with respect to the observer. If this loop is placed in a uniform magnetic field vec(B) , then torque acting on the loop is given by vec(tau) = vec(mu) xx vec(B) . Now answer the following questions: A uniformly charged insulating ring is rotated in a uniform magnetic field about its own axis, then

Assertion: A current I flows I flows along the length of an infinitely long straght and thin walled pipe. Then the magnetic field at any point inside the pipe is zero. Reason: oint vec(B).d vec(l) =mu I

Assertion : An emf vec(E) is induced in a closed loop where magnetic flux is varied. The induced vec(E) is not a conservative field. Reason : The line intergral vec(E).vec(dl) around the closed loop is non-zero.

Given three vectors vec a=6 hat i-3 hat j , vec b=2 hat i-6 hat ja n d vec c=-2 hat i+21 hat j such that vecalpha= vec a+ vec b+ vec c Then the resolution of the vector vecalpha into components with respect to vec aa n d vec b is given by a. 3 vec a-2 vec b b. 3 vec b-2 vec a c. 2 vec a-3 vec b d. vec a-2 vec b

The vectors vec(a), vec(b), vec(c ) and vec(d) are such that vec(a) xx vec(b) = vec(c ) xx vec(d) and vec(a) xx vec(c )= vec(b) xx vec(d) . Which of the following is/are correct? 1. (vec(a)- vec(d)) xx (vec(b) - vec(c ))= vec(0) 2. (vec(a) xx vec(b))xx (vec(c ) xx vec(d))= vec(0) Select the correct answer using the codes given below

The length of the perpendicular form the origin to the plane passing through the point a and containing the line vec r= vec b+lambda vec c is a. ([ vec a vec b vec c])/(| vec axx vec b+ vec bxx vec c+ vec cxx vec a|) b. ([ vec a vec b vec c])/(| vec axx vec b+ vec bxx vec c|) c. ([ vec a vec b vec c])/(| vec bxx vec c+ vec cxx vec a|) d.
