How did u guyz do in phys p1 ?
mr.incredible:
I need to check two other questions.
1. The one of the minimum resultant force of three forces.
2. That one of the stationary or moving charge and parallel or perpendicular electric field lines
Joseph_COOL:
How about the question where it says which graph is representing the force acting on an electron as distance x increases (x was the distance from negative to positive plate)??
my answer was A (the parabola)
anyone knows the right answer plz reply :D

force would be constant straight line parralel to x-axis

minimum is 0.
5N left and 3,4 N force on the right acting at 90 degree to each other
R^2=3^2 + 4^2
R=5
5-5 = 0 :D
charge can be stationary or moving and force is parallel to field
Ans i remember:
2.45 reading for screw gauge
neuclear reaction, neutrons conserved
2 masses stick v=10
P*V=energy
Q1 unit of volt ans was D
kirchoff one,conservation ofcharge
efficiency one was D mgsin/F
K=200 spring constant
A=1.3 acceleration
A doubled D double X remains same
5.5kw power
v=w/q e=w/q
and guys does anyone know the answer for the 2 same masses 1 station other collides with velocity V?

Are you sure that the force is parallel to the field ?? I chose stationary or moving charge and force is perpendicular to field.
For the spring constant, i got it 500 N/m.
The one you're asking about is D which was already a past paper question.
What did you chose for the rubber graph question ?

The force is parallel to the FIELD(pretty sure)
hmm what was D? was it 1/2 v to right and left?
I chose B, gradient of curve decreasing... (dunno if its correct)
and spring constant was 200 man we had to find the gradient of line
