1.	Which statement is incorrectA. `alpha-`rays have more penetrating power than `beta-` raysB. `alpha-`rays have less penetrating power than `gamma-`raysC. `beta-`rays have less penetrating power than `gamma`-raysD. `beta-`rays have more penetrating power than `alpha`-rays
Answer» Correct Answer - A The order of penetrating power is : `alpha lt beta lt gamma-`rays. It is due to lower mass and high speed
