A proton is about 1840 times heavier than an electron. When it is accelerated by a potential difference of 1kV, its kinetic energy will be:

Correct answer: C. 1 keV

  • A. 1840 keV
  • B. 1/1840 keV
  • C. 1 keV
  • D. 920 keV

Explanation

Kinetic Energy= eVEnergy depends upon charge not mass so same for proton and electronK.E. = eV = 1 KVe = 1 keV

About Electromagnetism

Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
