Q. Figure shows the path of an electron in a region of uniform magnetic field. The path consists of two straight sections, each between a pair of uniformly charged plates and two half-circles. The plates are named 1,2,3 and 4. Then

Q. A potential difference of 600 V is applied across the plates of a parallel plate capacitor placed in a magnetic field. The separation between the plates is 3 mm. An electron projected vertically upward, parallel to the plates, with a velocity of

2 \times 10^{6} m s^{- 1}

moves undeflected between the plates. Find the magnitude and direction of the magnetic field in the region between the capacitor plates. Find the magnitude and direction of the magnetic field in the region between the capacitor plates. Given the Charge of the electron
