To determine whether we can be sure that there is no magnetic field in a region of space where an electron is not deflected, we can analyze the forces acting on the electron. ### Step-by-Step Solution: 1. **Understanding the Forces on a Charged Particle**: An electron is a charged particle and experiences forces when it moves through electric and magnetic fields. The force due to an electric field \( \mathbf{E} \) is given by: \[ \mathbf{F}_E = q \mathbf{E} ...

The average electric field of electromagnetic waves in certain region of free space is 9 xx 10^(–4) NC^(–1) . Then the average magnetic field in the same region is of the order of

Assertion A beam of electron can pass undeflected through a region of E and B. Reason Force on moving charged particle due to magnetic field may be zero in some cases.

A beam consisting of protons and electrons moving at the same speed goes through athin region in which there is a magnetic field perpendicular to the beam. Protons and the electrons

Following experiment was performed by J.J. Thomson in order to measure ratio of charge e and mass m of electron. Electrons emitted from a hot filament are accelerated by a potential difference V. As the electrons pass through deflecting plates, they encounter both electric and magnetic fields. the entire region in which electrons leave the plates they enters a field free region that extends to fluorescent screen. The entire region in which electrons travel is evacuated. Firstly, electric and magnetic fields were made zero and position of undeflected electron beam on the screen was noted. The electric field was turned on and resulting deflection was noted. Deflection is given by d_(1) = (eEL^(2))/(2mV^(2)) where L = length of deflecting plate and v = speed of electron. In second part of experiment, magnetic field was adjusted so as to exactly cancel the electric force leaving the electron beam undeflected. This gives eE = evB . Using expression for d_(1) we can find out (e)/(m) = (2d_(1)E)/(B^(2)L^(2)) A beam of electron with velocity 3 xx 10^(7) m s^(-1) is deflected 2 mm while passing through 10 cm in an electric field of 1800 V//m perpendicular to its path. e//m for electron is
