Question

A particle (charge = -2.0 mC) moving in a region where onlyelectric forces act on it has a kinetic energy of 5.0J at point A.The particle subsequently passes through point B which has anelectric potential +2.5 kV relative to point A. Determin thekinetic energy of the particle as it moves through point B. A particle (charge = -2.0 mC) moving in a region where onlyelectric forces act on it has a kinetic energy of 5.0J at point A.The particle subsequently passes through point B which has anelectric potential +2.5 kV relative to point A. Determin thekinetic energy of the particle as it moves through point B.

Explanation / Answer

A particle (charge = -2.0 mC) moving in a region where onlyelectric forces act on it has a kinetic energy of 5.0J at point A.The particle subsequently passes through point B which has anelectric potential +2.5 kV relative to point A. Determin thekinetic energy of the particle as it moves through point B. kinetic energy the charge acquires when it passes through thepointB =Vq=2.5*1000*-2*10-3=-5J so the kinetic energy of the particle as it moves through pointB.=5-5= 0 J
