Every current through a wire produced a magnetic field. And since the magnetic field of Earth is weak, it will get attracted towards the wire.
Answer:
θ =28.07⁰
Explanation:
when van moves around an unbanked curve, horizontal component of normal force is equal to centripetal force
![F_{c}= F_{n} sin\theta](https://tex.z-dn.net/?f=F_%7Bc%7D%3D%20F_%7Bn%7D%20sin%5Ctheta)
---(1)
There is no motion in vertical direction, so vertical component of normal force is balanced with weight of block i.e.
----(2)
divide (1) and (2)
![\frac{F_{n}sin\theta}{F_{n}cos\theta} = \frac{\frac{mv^{2} }{r} }{mg}](https://tex.z-dn.net/?f=%5Cfrac%7BF_%7Bn%7Dsin%5Ctheta%7D%7BF_%7Bn%7Dcos%5Ctheta%7D%20%3D%20%5Cfrac%7B%5Cfrac%7Bmv%5E%7B2%7D%20%7D%7Br%7D%20%7D%7Bmg%7D)
![tan \theta=\frac{v^{2} }{rg}](https://tex.z-dn.net/?f=tan%20%5Ctheta%3D%5Cfrac%7Bv%5E%7B2%7D%20%7D%7Brg%7D)
![\theta=tan^{-1} \frac{v^{2} }{rg}](https://tex.z-dn.net/?f=%5Ctheta%3Dtan%5E%7B-1%7D%20%5Cfrac%7Bv%5E%7B2%7D%20%7D%7Brg%7D)
v = 28 m/s
r = 150 m
g = 9.8m/![s^{2}](https://tex.z-dn.net/?f=s%5E%7B2%7D)
θ = 28.07⁰
Answer:
