A) \[\frac{\omega M}{M+m}\]
B) \[{{a}_{c}}={{k}^{2}}{{r}^{2}}{{t}^{2}},\]
C) \[2mk{{r}^{2}}t\]
D) \[mk{{r}^{2}}{{t}^{2}}\]
Correct Answer: C
Solution :
For a closed circuit, cell supplies a constant current in the circuit. Equation of cell \[{{a}_{c}}={{k}^{2}}{{r}^{2}}{{t}^{2}},\] \[2mk{{r}^{2}}t\] \[mk{{r}^{2}}{{t}^{2}}\] ....(i) Similary, for \[m{{k}^{2}}{{r}^{2}}t\] \[m{{k}^{2}}r{{t}^{2}}\] ......(ii) From Eqs. (i) and (ii), we have \[1\text{ }km/h\] Substituting the value of r in Eq (i), we get \[\text{3 }km/h\]You need to login to perform this action.
