A) \[{{h}^{1/3}}{{G}^{2/3}}{{c}^{1/3}}{{A}^{1}}\]
B) \[{{h}^{2/3}}{{c}^{5/3}}{{G}^{1/3}}{{A}^{1}}\]
C) \[{{h}^{2/3}}{{c}^{1/3}}{{G}^{4/3}}{{A}^{1}}\]
D) None of these
Correct Answer: D
Solution :
| [d] (No option is correct) Bonus |
| Stopping potential \[\left( V \right)\propto {{h}^{x}}{{I}^{y}}{{G}^{z}}{{C}^{r}}\] |
| Here, h = planks constant \[=\left[ M{{L}^{2}}{{T}^{1}} \right]\] |
| \[I=current=\left[ A \right]\] |
| G = Gravitational constant \[=\left[ {{M}^{1}}{{L}^{3}}{{T}^{2}} \right]\] |
| and c = speed of light \[=\left[ L{{T}^{1}} \right]\] |
| \[\therefore \] and V = potential \[=\left[ M{{L}^{2}}{{T}^{3}}{{A}^{1}} \right]\] |
| \[\therefore \left[ M{{L}^{2}}{{T}^{3}}{{A}^{1}} \right]={{\left[ M{{L}^{2}}{{T}^{1}} \right]}^{x}}{{\left[ A \right]}^{y}}{{\left[ {{M}^{1}}{{L}^{3}}{{T}^{2}} \right]}^{z}}\text{ }{{\left[ L{{T}^{1}} \right]}^{r}}\]Comparing dimension of M, L, T, A, we get |
| \[y=1,x=0,z=1,r=5\] |
| \[\therefore \] |
