Answer:
16
Explanation:
The magnitude of the electrostatic force between two charged particles is given by
where
k is the Coulomb's constant
q1, q2 are the charges of the two particles
r is the separation between the particles
In this problem, the initial force between the particles is F.
Later, the distance between the two particles is increased by four, so
r' = 4r
So, the new force between the particles will be
So, the new force decreases by a factor of 16.
Answer:
The sweater will move towards you with a force of 35 N
Explanation:
In this problem, we have two forces acting on the sweater:
- A force of 65 N towards you
- A force of 30 N acting towards your brother
We can choose the direction "towards you" as positive, so that we can write the two forces as follows
Therefore, the net force acting on the sweater will be
And the positive sign (+) indicates that the direction of the net force is towards you, so the sweater will move towards your direction.
