Apoint charge q moves on the x-axis in the positive direction with a speed of 370 m/s. a point p is on the y-axis at y = +80 mm. the magnetic field produced at point p, as the charge moves through the origin, is equal to -0.80 μt along z-direction . when the charge is at x = +40 mm, what is the magnitude of the magnetic field at point p? (μ0 = 4π × 10-7 t ∙ m/a)

State the right hand rule of the direction of magnetic field in a conductor carrying current

Can anybody me with this? ? (picture included.)

Samir watches a 100-minute movie on his spaceship. maria's spaceshipe flies in the same direction as samir's spaceship but she observes his move to last 125 minutes and his spaceship to be 40 m long. how long does samir observe his own spaceship to be? according to an observer on earth, planet x is stationary. maria and samir depart earth on their spaceships at the same time, each flying at 0.5c. maria flies toward planet x and samir flies in the opposite direction. according to maria, her voyage to planet x takes 9 years. how many years does marias voyage take according to samir?
