اريد منكم حل سؤال 4 باللغه النجليزيه ضروري من اجل الأختبار
:(129):
The particle (mass m charge q) is confined to move on the x-axis. It moves under
the influence the electrostatic forces due the two charges (Q
a) Show that the net force on the particle is
kx/(x^2+b^2)^3/2=fx
0e pwhere k = qQ /2
¥=b) Find the potential energy function V(x), take V=0 at x
?c) If the particle starts from rest at x = b, what will its speed be at x = 2b
Give your answers in terms of k and b.
