Question
Three concentric spherical shells have radii a, b and c(a<b<c) and have surface charge densities , - andrespectively. If VA ,VBand VC denote the potentials of the three shells, then,for c=a+b , we have: (1) VC= VB (IS NOT EQUALTO) VA (2) VC(IS NOT EQUALTO) VB(IS NOT EQUALTO) VA. (3) Vc = VB = VA (4) VC = VA(IS NOTEQUAL TO) VB. Three concentric spherical shells have radii a, b and c(a<b<c) and have surface charge densities , - andrespectively. If VA ,VBand VC denote the potentials of the three shells, then,for c=a+b , we have: (1) VC= VB (IS NOT EQUALTO) VA (2) VC(IS NOT EQUALTO) VB(IS NOT EQUALTO) VA. (3) Vc = VB = VA (4) VC = VA(IS NOTEQUAL TO) VB. (4) VC = VA(IS NOTEQUAL TO) VB.
Explanation / Answer
Given : Three concentric spherical shells have radii a, b and c(a<b<c) and have surface charge densities , - andrespectively. If VA ,VBand VC denote the potentials of the three shells, then,for c=a+b , we have (2) VC(IS NOT EQUALTO) VB(IS NOT EQUALTO) VA. (2) VC(IS NOT EQUALTO) VB(IS NOT EQUALTO) VA. I hope it helps you
