A triangular loop is started to being pulled out at t=0 from a uniform magnetic field with a constant velocity v. Total resistance of the loop is constant and equals to R. Then the variation of power produced in the loop with time will be:A. Linearly increasing with time till whole loop comes out.B. Increases parabolically till whole loop comes out.C. P is proportional to t^ 3 till whole loop comes outD. Will be constant with time

AB is a current carrying conductor in the plane of the paper as shown in the figure below. (i) What is the direction of the magnetic field produced by it at point ‘X’? Write the statement of the rule used to find the direction of field lines. (ii) If the polarity of the battery connected to the wire is reversed, how would the direction of the magnetic field be changed? (iii) Point ‘X’ is at a distance r1 and point ‘Y’ is at a distance r2 (r1
