MCQ
Which ray contain positively charged particle
- ✓$\alpha -$ ray
- B$\beta -$ ray
- C$\gamma -$ ray
- D$X-$ ray
✓
Answer
Correct option: A.
$\alpha -$ ray
a
$\alpha$ - Particles are doubly charged helium nuclei. They are positively charged and gets deflected towards negatively charged plates.
$\alpha$ - Particles are doubly charged helium nuclei. They are positively charged and gets deflected towards negatively charged plates.
$\Rightarrow He ^{2+}$
$\beta$ - particles are fast moving electrons.
$\Rightarrow e ^{-}$
$\gamma$ - rays are electromagnetic waves.
$\Rightarrow$ Em wave
$X$ - rays are electromagnetic waves.
$\Rightarrow$ Em wave.
