Vertical Deflection of Electron: 1.1×107 m/s & 3.2×10-16 N

as long as i remember thesedoes'nt the effect of gravity depend on mass a =f/m?

or is this out of the rhealm of Newtons laws?

But what is F in this case?

 

[Nathanael]

does'nt the effect of gravity depend on mass a =f/m?

No because "f" in the case of gravity is proportional to mass, so it cancels out.
This is the reason that the acceleration of gravity near Earth (9.8 m/s/s) is the same for all objects.

i don't know if I am cut out for physics

In my opinion, whether you're "cut out for physics" is more dependent on your work ethic than on your natural ability. You can lack natural ability and still make it by hard work, and if you have natural ability you still won't make it without hard work.

But what is F in this case?

ok, g=g is the bottom line

There is also the idea that despite finding the problems previously difficult, you now find them easy. All Physicists, good or bad find problems they can't solve. what separates the good from the bad is their ability to learn and persist. You seem to have done both here.

Yea, I am just trying get quicker at solving physics problems. I will fail an exam if i take as long as i do to solve these homework problems

what do you think is the best way to solve physics problems quickly? i think doing a bunch of practice problems would be the only way.

Drawing a diagram is almost always useful but you seem to already do that well. Understanding e.g. formulae is always more important that simply memorising. Practice problems are helpful. Make sure you try doing questions without looking at the answer sheets.

and the difficult part about these problems is that i can be asked a problem just like the one previously solved but it will have

to me physics problems are difficult in that the technique used to solve the problem is not given, as opposed to a math class where you'd be solving a set of problem with a common technique that works for each problem.

A skill which should come with practice and understanding.
