A) slope of the line
B) product of slope of the line and charge on the electron
C) intercept along Y-axis divided by charge on the electron
D) product of intercept along X-axis and mass of the electron
E) product of slope and mass of the electron
Correct Answer: B
Solution :
Einsteins equation is \[V=\frac{hv}{e}-\frac{h{{v}_{0}}}{e}\] Here, slope of line \[=\frac{h}{e}\] \[\Rightarrow \] \[h=\] Plancks constant \[=slope\times e\]
