Answer
given,
height of counter = 1.20 m
horizontal distance from base = 1.6 m
a) velocity of mug = ?
using equation of motion
t = 0.495 s
speed of the mug
s_x = v x t
1.6 = v x 0.495
v = 3.23 m/s
b) final velocity of mug in y direction
again using equation of motion
v² = u² + 2 a s
v²= 0 + 2 x 9.8 x 1.2
v = √23.52
v_y = 4.85 m/s
now, direction
-14.4 N is the electric force between a point charge and a point charge if they are separated by a distance of 5.0 cm.
The electrostatic force between two-point charges is given by:
where,
is the Coulomb's constant
q1 and q2 are the two charges
r is the distance between them
In our problem, charge 1 is
while charge 2 is
and their distance is
r=5.0 cm=0.05 m
So, the electrostatic force between them is
And the negative sign means the force is attractive, because the two charges have opposite sign.
<h3>What is electric force?</h3>The electrostatic force between two-point charges separated by a distance is directly proportional to the multiplication of the magnitudes of the charges and inversely proportional to the square of the distance between the charges.
<h3>What are some electrostatic force examples?</h3>- The force of attraction of the plastic wrap to one’s hand and later when hand is removed from the wrap.
- The attraction of paper to a charged scale by rubbing to hair.
- The apparently spontaneous explosion of grain silos.
- Photocopier & laser printer operation.
