Correct Answer: 2
Solution and Explanation
Let number of α particles are nα and β particles are nβ so
4nα = 230 – 214
\(⇒\) nα = 4
nβ = 84 – (90 – 2nα)
nβ = 2
So \(\frac{n_α}{n_β}=2\)

Top Questions on Radioactivity
- A region in the form of an equilateral triangle (in x-y plane) of height \( L \) has a uniform magnetic field \( \mathbf{B} \) pointing in the \( +z \)-direction. A conducting loop PQR, in the form of an equilateral triangle of the same height \( L \), is placed in the x-y plane with its vertex \( P \) at \( x = 0 \) in the orientation shown in the figure. At \( t = 0 \), the loop starts entering the region of the magnetic field with a uniform velocity \( \mathbf{v} \) along the \( +x \)-direction. The plane of the loop and its orientation remain unchanged throughout its motion.
