1.	A proton is about 1840 times heavier than an electron. When it is accelerated by a potential difference of 1k V, its kinetic energy will be
Answer» 1840 keV 1/1840 ke V 1 keV 920 keV Solution :ENERGY acquired by ELECTRON (as K.E.) on being ACCELERATED by a potential difference of 1kV = 1KEV. As proton has the same CHARGE and as energy = potential difference `xx` charge, hence proton will have the same kinetic energy
