Answer:

m=1000kg

v=72km/h=20m/s

Work = different of kinetic energy

W= ½ mv ²

W= ½ ×1000×20×20= 400000J

also written as 4×10^5 J

thank you

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 .
