An electron is projected as in figure with kinetic energy K, at an angle `theta=45^(@)` between two charged plates. The magnitude of the electric field so that the electron just fails to strike the upper plate, should be greater than:

Two long parallel plates A and B are separated by a distance of 4 cm with an electric field of 45 . 5 Vm^(-1) between the plates normally from plate A to plate B , as shown in the figure. An electron is projected from plate A with velocity v at an angle of 30^(@) with the surface of plate A . The maximum value of v so that the electron does not hit plate B is (Assume gravity free space, charge of electron = 1.6 xx 10^(-19) C and mass of electron = 9 . 1 xx 10^(-31) kg )

An electron of kinetic energy K is projected between two charged plats at an angle 60^(@) as shown in figure. If electrons doesn't reach to the upper plate just before striking then the magnitude of electric field will be more than:

A potential difference of 600 V is applied across the plates of a parallel plate condenser. The separation between the plates is 3 mm. An electron projected vertically, parallel to the plates, with a velocity of 2xx10^(6)m//s moves undeflected between the plates. Find the magnitude of the magnetic field (in T) in the region between the condenser plates. (Neglect the edge effects) square . (Charge of the electron =1.6xx10^(-19)C )

An electron enters the region between the plates of a parallel plate capacitor at an angle theta to the plates. The plate width is l , the plate separation is d . The electron follows the path shown just missing the upper plate. Neglect gravity. Then,

An electron is projected with an initial velocity of 10^(7)ms^(-1) into an electric field between two parallel plates 1 cm apart. The electron enters the field at a point midway between the plates. If the electron just misses the positivity charged plate as it emerges from the field, find the magnnitude of the electric density between the plates. (Length of each plate is 2 cm, mass of electron= 9xx10^(-31) kg and charge of electron =1.6xx10^(-19) C)

A uniform electric field of strength 2xx10^3NC^-1 is established between two parallel plates of length 0.1 m held horizontally at a distance 0.02 m apart. An electron is projected at a speed of 6xx10^6 ms^-1 making an angle 45^@ as shown in the figure The field is directed vertically upwards. Will the electron strike the either plate? If it strikes the plate, where does it do so?
