A) \[\text{1}.\text{5}\times \text{l}{{0}^{\text{6}}}\]
B) \[\text{1}.\text{78}\times \text{l}{{0}^{\text{8}}}\]
C) \[\text{2}.\text{25}\times \text{l}{{0}^{\text{8}}}\]
D) \[\text{2}.\text{67}\times \text{l}{{0}^{\text{8}}}\]
Correct Answer: C
Solution :
Since, [iv = constant \[\Rightarrow \] \[{{\mu }_{g}}{{v}_{g}}={{\mu }_{w}}{{v}_{w}}\] \[\Rightarrow \] \[\frac{3}{2}(2\times {{10}^{8}})=\frac{4}{3}{{v}_{w}}\] \[\Rightarrow \] \[{{v}_{w}}=2.25\times {{10}^{8}}m/s\]You need to login to perform this action.
