Answer:
Magnetic field, B = 0.042 T
Explanation:
It is given that,
Speed of charged particle, ![v=8.2\times 10^3\ m/s](https://tex.z-dn.net/?f=v%3D8.2%5Ctimes%2010%5E3%5C%20m%2Fs)
Angle between velocity and the magnetic field, ![\theta=87](https://tex.z-dn.net/?f=%5Ctheta%3D87)
Charge, ![q=5.7\ \mu C=5.7\times 10^{-6}\ C](https://tex.z-dn.net/?f=q%3D5.7%5C%20%5Cmu%20C%3D5.7%5Ctimes%2010%5E%7B-6%7D%5C%20C)
Magnetic force, F = 0.002 N
The magnetic force is given by :
![F=qvB\ sin\theta](https://tex.z-dn.net/?f=F%3DqvB%5C%20sin%5Ctheta)
B is the magnetic field
![B=\dfrac{F}{qv\ sin\theta}](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7BF%7D%7Bqv%5C%20sin%5Ctheta%7D)
![B=\dfrac{0.002}{5.7\times 10^{-6}\times 8.2\times 10^3\times sin(87)}](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B0.002%7D%7B5.7%5Ctimes%2010%5E%7B-6%7D%5Ctimes%208.2%5Ctimes%2010%5E3%5Ctimes%20sin%2887%29%7D)
B = 0.042 T
So, the strength of the magnetic field is 0.042 Tesla. Hence, this is the required solution.
