An electron travelling with a speed of `5xx10^(3) ms^(-1)` passes through an electric field with an acceleration of `10^(12)ms^(-2)`. (i) How long will it take for the electron to double its speed ?(ii) What will be the distance covered by the electron in this time?

An electron moving with velocity of 5 xx 10^(4) m/s. When it enters into an electric field, it gains an acceleration of 1 xx 10^(15) . In how much time, velocity of electron will become double of initial velocity?

An electron is emittied with a veloctiy of 5 xx 10 ^(6) ms^(-1) . It is accelerated by an electric field in the direction of initial velocity at 3xx 10^(14) ms^(-2) . If its final velocity is 7xx10^(6) ms^(-1) calculation the distance coverd by the electron .

An electron moving with a velocity of 5 xx 10^(4)ms^(-1) enters into a uniform electirc field and acquires a uniform acceleration of 10^(4)ms^(-2) in the direction of its initial motion. (i) Calculate the time in which the electron would acquire a velocity double of its initial velocity. (ii) How much distance the electron would cover in this time ?

An electron moving with a speed of 2.5 xx 10^(7) ms^(-1) is deflected by an electric field of 1600 Vm^(-1) perpendicular to its circular path. If the radius of the electron trajectory is 2.3 m, calculate the e/m for the electron.

An electron moving with the speed 5xx10^(6) per sec is shot parallel to the electric field of intensity 1xx10^(3)N//C . Field is responsible for the retardation of motion of electron. Now evaluate the distance travelled by the electron before coming to rest for an instant (mass of e= 9xx10^(-31)Kg charge = 1.6xx10^(-19)C)

An electron beam moving with a speed of 2.5xx10^(7) ms^(-1) enters into the magnetic field 4xx10^(-3) Wb//m^(2) directed perpendicular to its direction of motion. Find the intensity of the electron moves undeflected .

An electron beam passes through a magnitic field of 2xx10^(-3) "weber"//m^(2) and an electric field of 1.0 xx 10^(4) "volt/m" both acting simultaneously. If the electric field is removed, what will be the radius of the electron path ?

An electron is released with a velocity of 5xx10^(6)ms^(-1) in an electric field of 10^(3)NC^(-1) which has been applied so as to oppose its motion. What distance would the electron travel and how much time could it take before it is brought to rest?
