An electron beam moves toward a cathode ray tube screen, which is 30 cm away from the negative electrode. The electrons are accelerated by a potential difference of 14 kV. Estimate the maximum displacement of the electron beam caused by Earth's magnetic field. The average magnetic field at the surface of Earth is roughly BE = 45×10−6T. answer with units

Q 11) An electron beam moves toward a cathode ray tube screen, which is 20 cm away from the negative electrode. The electrons are accelerated by a potential difference of 18 kV. Estimate the maximum displacement of the electron beam caused by Earth's magnetic field. The average magnetic field at the surface of Earth is roughly BE = 45×10^−6T. Express your answer with the appropriate units.

Older televisions display a picture using a device called a cathode ray tube, where electrons are emitted at high speed and collide with a phosphorescent surface, causing light to be emitted. The paths of the electrons are altered by magnetic fields. Consider one such electron that is emitted with an initial velocity of 1.85 107 m/s in the horizontal direction when magnetic forces deflect the electron with a vertically upward acceleration of 5.45 1015 m/s2. The phosphorescent screen is a...

Older televisions display a picture using a device called a cathode ray tube, where electrons are emitted at high speed and collide with a phosphorescent surface, causing light to be emitted. The paths of the electrons are altered by magnetic fields. Consider one such electron that is emitted with an initial velocity of 2.05 x 10^7 m/s in the horizontal direction when magnetic forces deflect the electron with a vertically upward acceleration of 5.30 x 10^15 m/s2. The phosphorescent screen...

019 10.0 points A cannon fires a 0.579 kg shell with initial velocity Vi-11 m/s in the direction θ 43° above the horizontal. The shell's trajectory curves downward be- cause of gravity, so at the timet 0.55 s the shell is below the straight line by some vertical distance ΔΙι Find this distance Ah in the absence of air resistance. The acceleration of gravity is 9.8 m/s2. Answer in units of m

An electron with an initial velocity v0 = 2.30×105 m/s enters a region 1.0 cm long where it is electrically accelerated (see the figure). It emerges with velocity v = 5.10×106 m/s. What was its acceleration, assumed constant? (Such a process occurs in the electron gun in a cathode-ray tube, used in television receivers and oscilloscopes.)
