Question

pls give me the answer

Answer 1

Hi there,

Here's an easy way to solve this.

Let charge of proton be +e, then charge of particle will be +2e. Similarly let mass of proton be m, then mass ofparticle will be 4m.

Now, specific charge = charge / mass of the substance.

For proton, specific charge = e/m

For alpha particle, specific charge = 2e/4m

Therefore there ratio is : (e/m) * (4m/2e) = 2:1

hopefully this is helpful
