Answer» a) 0 b) 2iR c) 2iRExplanation:magnetic force= iLbsintheta here L is displacementdisplacement between a and b which is in SEMI circular path is diameter ie 2Ra) angle between L and B is 0 DEGREE ie sin 0 is 0F= 0b) angle between L and B is 90 degree ie sin 90 is 1F= I ×2R×1 = 2iRc) angle between L and B is 90 degree ie sin 90 is 1F= 2iR note : displacement direction is from a to b |
