We have this complex reasoning question (at school) with this weird situation, anyway they say incorporating every part gives the formula(adsbygoogle = window.adsbygoogle || []).push({});

[tex] V = mgR tan (\theta) / B^2 L^2 cos (\theta) [/tex]

Where V is the velocity

m is the mass

g is the acceleration (gravity)

B is the magnetic field strength

R is the resistance

L is the length

Now this question is a proof and i must prove it using known physics formula's (mainly from electricity).

The closest i got was to proving it was

[tex] V = mgr / B^2 L^2 sin^2(\theta) [/tex]

If anyone could help me would be greatly appreciated.
