Given that,
First charge = Q₁
Second charge = Q₂
The potential experienced by Q2 due to Q1 increases
We know that,
The electrostatic force between two charges is defined as
Where,
k = electrostatic constant
= first charge
= second charge
r = distance
According to given data,
The potential experienced by Q₂ due to Q₁ increases.
We know that,
The potential is defined from coulomb's law
If r decrease then V will be increases.
If V decrease then r will be increases.
Since, V is increases then r will decreases that is moving Q₁ closer to Q₂.
Hence, Moving Q₁ closer to Q₂.
(c) is correct option.
Answer:
west
Explanation:
The acceleration of an object is equal to the rate of change of velocity of the object, and it is given by:
where
u is the initial velocity
v is the final velocity
t is the time elapsed
For the object in this problem:
u = 65 m/s east is the initial velocity
v = 25 m/s east is the final velocity
t = 10 s is the time elapsed
Substituting, we find the acceleration:
And the negative sign tells that the direction of the acceleration is opposite to the direction of the velocity: so, the acceleration is west.
