How was the Physics Unit 4 exam?

[Agent Z]

hey everyone, for the tension question. i added the C.F and the weight and got 7N. i was supposed to subtract them and get 3N but i dont know what happened. anyways my calculations for the C.F and W are correct. how many marks would i lose. is here a follow through for the graph question??

Tension = mv^2/r - mg, so answer was 3.
How many marks you might lose is upto the person marking and how lenient Edexcel are.

how much was the electric field question??

how much was the electric field question??

4 marks I reckon.

I mean what was your answer

Haha. I am not the right person to ask mate! I do not remember. Neither do I want to. I got that wrong.

For that electric field goofy, if we used F=kQ1Q2/r^2, what is the k value in it?

 

[Humaid Mehdi]

Nooooooooooooo..!!!! I messed up! K was a constant. I didnt write its value. Otherwise my answer was going in the right direction. I hate my senses!

This forum is full of nerds...how can you call that paper "easy"?

Did you find anything particularly hard besides the two graphs and electric field question?

well, those three things messed up my brain at the exam hall.

Seems much smoother than Unit 4. But then again, that's just my opinion.

same opinion

8.99 × 10⁹

guys what was the electrical field strength on point C 0.33m away? :/

 

[aldamon]

You solve that by taking the vertical component of the magnetic field at point b, they gave you the angles.....it's so easy but I only realized the answer after I came home >.> =3

 

[aldamon]

Give an estimate of your lost marks....

what was the acceleration of the particle in the electrical field question?
