There exists a region of electric field with potential difference of 2

1.	There exists a region of electric field with potential difference of 25 V as shown in figure. An electron enters this region at speed of v = 3 ×106 m/s at angle of α and emerges out of region at angle β. The sin αsin β is [Electric field exist in given region only]e=1.6×10−19,m=9.1×10−31 (2 decimal places)
Answer» There exists a region of electric field with potential difference of 25 V as shown in figure. An electron enters this region at speed of v = 3 $\times 10^{6}$ m/s at angle of $α$ and emerges out of region at angle $β$ . The $\frac{s i n α}{s i n β}$ is [Electric field exist in given region only] $e = 1.6 \times 10^{-} 19, m = 9.1 \times 10^{-} 31$ (2 decimal places)
