A) 1
B) 2
C) \[\frac{1}{2}\]
D) None of these
Correct Answer: A
Solution :
If l and d be length and thickness of plate A, then \[{{R}_{A}}=\rho \frac{l}{a}=\frac{\rho l}{l\times d}=\frac{\rho }{d}\] and \[{{R}_{B}}=\,\frac{\rho \times 2l}{2l\times d}=\frac{\rho }{d}\] \[\therefore \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\frac{{{R}_{A}}}{{{R}_{B}}}=1\]You need to login to perform this action.
