What magnetic field strength will allow the electrons to pass through without being deflected?

Explanation:

If magnetic field exists parallel  to the direction of motion of electron , no force will act on the electrons and hence there will be no deflection in them .

In such cases , the magnitude of magnetic field is immaterial . No matter how high or low magnitude of magnetic field be , if it is parallel to the velocity of electron , it will not be deflected as the force created on them will be zero.

Only in case magnetic field  makes some angle with the direction of velocity , force will be created and electron will be deflected .

i think the answer would be reserve.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
