Question

A radium source which emits α, β and gamma radiations is placed in a lead block. The beam of radiations emitted is split into thre parts by a strong magnetic field. Which type of radiations is responsible for each of the marks X, Y and Z in this figure and differentiate with respect to charge, and nature.

• A. X =Gamma Radiations , Y = Alpha Particles, Z = Beta Particles
• B. X = Alpha Particles , Y = Gamma Radiations , Z = Beta Particles
• C. X = Alpha Particles , Y = Beta Particles , Z = Gamma Radiations
• D. X = Beta Particles, Y = Gamma Radiations , Z = Alpha Particles

Answer 1

The correct option is B

X = Alpha Particles , Y = Gamma Radiations , Z = Beta Particles

Flemings Left Hand Rule was used for positively charged species which is alpha particles and gamma being electromagnetic radiation doesn’t deviate in a magnetic field.
