Assertion: A beam of electrons deflects more than a beam of a-particles in an electric field. Reason: Electrons possess negative charge while \[\alpha \] -particles possess positive charge,A) A
B) B
C) C
D) D
E) E
Correct Answer: B
Solution :
It is true that \[\beta \] particles deflect more than a beam of \[\alpha \] particles in an electric field but this is because \[\beta \]particles are lighter as compared to \[\alpha \]-particles. This is also true that \[\beta \] particles are negatively charged and a particles are positively charged.
