Question

Two paths (path 1 and 2) followed by charge particles in magnetic field is shown in the figure. All the charge particles enters the magnetic field at A with equal kinetic energy. Choose the incorrect statement

• A. If 1 is $\alpha$-particle then 2 may be deutron
• B. If 1 is proton then 2 may be deutron
• C. If 1 is $\alpha$-particle then 2 must be proton
• D. If 1 is deutron then 2 may be proton

Answer 1

The correct option is A If 1 is $\alpha$-particle then 2 may be deutron

Since $\alpha$ particles $\left(H{e}^{2+}\right)$possesses greater charge than den-tron $D^{1+}$ it will be deflected more in a magnetic field since $=Bqv$ where greater charge implies greater force experienced.
