Question

A particle has a change of + 1.3 muC and moves from point A to point B, a distance of 0.21 m. The particle experiences a constant electric force, and its motion is along the line of action of the force. The difference between the particle's electric potential energy at A and B is EPEA - EPEB = + 7.2 times 10 - 4]. (a) Find the magnitude of the electric force that acts on the particle. (b) Find the magnitude of the electric field that the particle experiences. The number of significant digits is set to 3; the tolerance is + / - 2% the number of significant digits is et to 3; the tolerance is + / - 2%

Explanation / Answer

a) 7.2*10^(-4)/0.21 =0.0034 N b) E=0.0034/(1.3*10^(-6)) =2615.38 N/C
