Particles of charge +75, +48, and -85μC are placed in a line. The center one is 0.35 m from each of the others. Calculate the net force on each charge due to the other two.

Respuesta :

+X axis is passing through from +75 to +48. then to _83
Now force on +75 due to +48 is being repulsive, with the direction -X, So the X component of force is negative.
Force on +75 due to -85 is attractive, with the direction of +X.
∴ The X component of force is positive
K is always constant and positive.
