A) \[{{S}_{1}}:{{S}_{2}}:{{S}_{3}}=1:5:9\]
B) \[{{S}_{1}}:{{S}_{2}}:{{S}_{3}}=1:3:5\]
C) \[{{S}_{1}}:{{S}_{2}}:{{S}_{3}}=9:2:3\]
D) \[{{S}_{1}}:{{S}_{2}}:{{S}_{3}}=1:1:1\]
Correct Answer: B
Solution :
[b] \[{{S}_{1}}=\frac{1}{2}\,\,g\,\,{{\left( \frac{1}{2} \right)}^{2}},\]\[{{S}_{1}}+{{S}_{2}}=g{{(1)}^{2}}\] \[\frac{1}{2}\,\,g\,\,{{\left( \frac{3}{2} \right)}^{2}}=S+{{S}_{2}}+{{S}_{3}}\]You need to login to perform this action.
