A) \[\Omega \]
B) \[\Omega \]
C) \[\phi \]
D) \[\phi ={{\phi }_{0}}+4t\]
Correct Answer: B
Solution :
In \[\frac{1}{4\lambda }\] \[4\lambda \] \[2\lambda \] or \[\frac{1}{2\lambda }\] ??(i) In \[\frac{qvR}{2}\] \[qv{{R}^{2}}\] or \[\frac{qv{{R}^{2}}}{2}\] ??.(ii) From Eqs. (i) and (ii), we get \[qvR\] \[{{L}_{A}}\] \[{{L}_{B}}\] If n is the refractive index of material of slab (glass) w.r.t. air, then \[{{L}_{A}}>{{L}_{B}}\] For small angle, \[{{L}_{A}}={{L}_{B}}\] or \[{{L}_{A}}\] and \[{{L}_{B}}\][\[{{L}_{A}}<{{L}_{B}}\] \[\Omega \] and \[\Omega \] if \[\pi \] is small] \[\pi \] or \[\pi \]You need to login to perform this action.
