Question
Coulomb's Law is an inverse square law in which the electric field is is along a line to the source charge and given by
with the usual meaning of k as a constant determined by units, q the source charge, and r the distance to that charge.
When you know the electric field, how do you find the force on a charge q?
A. The force depends on q/m also
B. The force is Er2
C. The force is the same as the field
D. The force is E/r2
E. The force is qE
A. The force depends on q/m also
B. The force is Er2
C. The force is the same as the field
D. The force is E/r2
E. The force is qE
Explanation / Answer
E = k Q / r^2
force, F = q E = k q Q / r^2
Ans: (E)
