STATEMENT-I: It is possible for a thermal neutron to be absorbed by a nucleus where as proton or an alpha particle would need a much larger amount of energy for being absorbed by the same nucleus. STATEMENT-II: Neutron is electically neutral but proton and alpha particle are positively charged.

An alpha particle of positive charge +2e is compelled to rotate along a circular path of radius r in a cyclotron with linear speed v. The magnetic moment of the closed loop is

A beam of electrons deflects more than a beam of alpha-"particles" in an electric field. Electrons possess negative charge while alpha-"particles" possess positive charge.

Assertion : During alpha -particles scattering experiment, 99% of the alpha -particles get deflected through very large angles. Reason : The nuclei of atoms are positively charged and repel alpha -particles which are also positively charged.
