Comment on student's suggestion: coil is stationary, so no induced emf or current to calculate magnetic flux density

i wrote that voltmeter cant be connected in series can it be right?

Iam expecting 85+ in p4 and i had A in AS with components A in p1 A in p2 and B in p3.. Are there any chances for A*

I don't thinks so! Charge was different as only charge on b was given and the in question it was mentioned clearly that calculate the mass of both isotopes, hence they had same mass! And part b men we had to show the charge on A by using the diameter given and taking the same mass! Though, It was a bit confusing initially.
