1.	`e//m` ratio in case of anode ray experiment is different for different gases. The ion of gases formed after the ejection of electron are different of gas is different.A. If both assertion and reason are true and the reason is the correct explanation of the assertion.B. If both assertion and reason are true but reason is not the correct explanation of the assertion.C. If assertion is true but reason is falseD. If assertion is false but reason is true.
Answer» Correct Answer - A (a) `e//m` ratio for particles in anode rays is different for different gases as different produce different positively charged particles upon ionisation.
