Ball at top of loop, mv^2/r -mg so reaction force has to be greater than zero to stay in contact
Ball at bottom of loop. 2.7 ms^-1 that was bloody hard
Momentum coin-1.6 ms^-1
6 marker on coin, resultant force =-km, use suvat, another bs question
6 marker muons, relativistic time dilation so half life and distance travelled increases
Cable 19.2kW
Flower field strength idek, but wasn’t radial

Silicon and 69 degrees for the last page.
To prove collision was inelastic do 1/2 mv^2 before and after.
Mass was like 8.8 X 10 ^ something cant remember exactly
State the 2 conservation laws: I said Energy and momentum.

For the derive equation:
Use I=nAvQ with q=e and A=d x t, and rearranging for v then plug in F= bqv. Make it equal to Vhall X q/r then rearrange.
Units on either side of the derive equation gave me Nm/C.

For anyone wondering how to derive v hall
F=E/e
E=V/d in this case as d was separation
F=V/ed
So F=Bqv
Bev=V/ed
I=nave
v=I/nae
BeI/nae=V/ed
Bl/nae=v/d
BId/nae=V
D/a is the 1/t thing so
Bl/net=V
Very hard

Was 69 degrees, u had to use tan and was angle to horzintoanl so was vertical/horizontal as tan=o/a

But the vertical one was the larger, so gonna be greater thann45degrees

You’ll get a mark for “use of inverse tan”
