Describe a situation in which an electron will be affected by an external electric field but will not be affected by an external
irina [24]

Answer:

Explanation:

Situations in which an electron will be affected by an external electric field but will not be affected by an external magnetic field

a ) When an electron is stationary in the electric field and magnetic field , he will be affected by electric field but not by magnetic field. Magnetic field can exert force only on mobile charges.

b ) When the electron is moving parallel to electric field and magnetic field . In this case also electric field will  exert force on electron but magnetic field field will not exert force on electrons . Magnetic field can exert force only on the perpendicular component of the velocity of charged particles.

Situations when electron is affected by an external magnetic field but not by an external electric field

There is no such situation in which electric field will not affect an electron . It will always affect an electron .

A volleyball is spiked so that its incoming velocity of +2.63 m/s is changed to an outgoing velocity of -20.2 m/s. The mass of t
earnstyle [38]

Answer:

The impuise is 7.9905 kg*m/s

Explanation:

Step one:

given data

v1= +2.63m/s

v2=-20.2m/s

mass m= 0.350kg

Step two:

From the expression for impulse

Ft= mΔv

substituting our data into the expression we have

Ft= 0.35*(-20.2-2.63)

Ft= 0.35*22.83

Ft=7.9905 kg*m/s
