An electron gun `G` emits electons of energy `2 keV` travelling in the positive x-direction. The electons are required to hit the spot `S` where `GS=0.1 m`, and the line `GS` makes an angle of `60^@` with the x-axis as shown in figure. A uniform magnetic field `B` parallel to `GS` exists in the region outside the electron gun.

find the minimum value of `B` needed to make the electrons hit `S`.

An electron gun G emits electrons of energy 2ke V travelling in the positive x- direction . The electrons are required to hit the spot S where GS = 0.1m , and the line GS makes an angle of 60^(@) with the x-axis as shown in the fig. A uniform magnetic field vec(B) parallel to GS exists in the region outside the electron gun. Find the GS exists in the region outside the electron gun. Find the minimum value of B needle to make the electron hit S .

A uniform electric field and a uniform magnetic field are acting along the same direction in a certain region. If an electron is projected in the same direction then the electron

One electron gun is firing electrons with a speed V as shown in the figure. There is a target P which is to be hit. Electrons emerge from point 0 and line OP makes an angle with the direction of velocity of electrons. The length of OP is L.A uniform magnetic field B is applied parallel to line OP. Charge on the electron ise and the mass of electrons is m. What minimum magnetic field is needed so that electrons may hit the target P?

In vacuum an electron of energy 10 keV hits tungsten target, then emitted radiation will be
