Answer #1

1)Milliampere is the unit of Electric current and seconds is the unit of time. Hence, mAs is the unit of current*time that is Electrostatic charge

Hence,option e is correct

2)x rays are not affected by electrostatically charged matter because they carries zero charge.

Others,alpha particle,beta particles,electrons,protons carries some charges so they will experience electrostatic force and will be affected by a charged matter.

Hence,option e is correct.
