Question
Part A. What are the magnitudes of the accelerations of the plastic bead and the glass bead? Part B. What are the directions of the accelerations of the plastic bead and the glass bead? a. The beads are moved in he same direction. b. The beads are repulsed to one another. c. The beads are attracted to one another. What are the directions of the accelerations of the plastic bead and the glass bead? a. The beads are moved in he same direction. b. The beads are repulsed to one another. c. The beads are attracted to one another. A 1.7g plastic bead charged to -3.8nC and a 3.9g glass bead charged to 17.9nC are 2.3cm apart (center to center). What are the magnitudes of the accelerations of the plastic bead and the glass bead? What are the directions of the accelerations of the plastic bead and the glass bead? The beads are moved in he same direction. The beads are repulsed to one another. The beads are attracted to one another.Explanation / Answer
Plastic bead,
m1 = 1.6 x10^-3 kg
q1 = - 4.1x10^-9 C
Glass bead,
m2 = 3.7x 10^-3 kg
q2 = 18.9 x 10^-9 C
Distance between the two = d = 2.5 x 10^-2 m
Force of attraction between them is
F = 9x10^9 x q1x q2 / d^2 = 1.1159 x 10^-3 N
They move towards each other.
Acceleration of the plastic and glass beads respectively are,
a1 = F / m1 = 0.6974 m /s
a2 = F / m2 = 0.30 m /s
