A) \[\frac{{{\lambda }_{1}}+{{\lambda }_{2}}}{2Dd}\]
B) LCM of \[\frac{{{\lambda }_{1}}D}{d}\]and \[\frac{{{\lambda }_{2}}D}{d}\]
C) \[\left( {{\lambda }_{1}}-{{\lambda }_{2}} \right)\frac{2D}{D}\]
D) HCF of \[\frac{{{\lambda }_{1}}D}{d}\] and \[\frac{{{\lambda }_{2}}D}{d}\]
Correct Answer: B
Solution :
[b] \[\frac{{{n}_{1}}D{{\lambda }_{1}}}{d}=\frac{{{n}_{2}}D{{\lambda }_{2}}}{d};\] \[\frac{{{n}_{1}}}{{{n}_{2}}}=\left( \frac{D{{\lambda }_{2}}}{d} \right)/\left( \frac{D{{\lambda }_{1}}}{d} \right)\] LCM of \[\frac{D{{\lambda }_{1}}}{d}\]and \[\frac{D{{\lambda }_{2}}}{d}\]You need to login to perform this action.
