Answer:
The third charge placed is 0.80 m.
Explanation:
Given that,
Distance = 0.57 m
First charge = q
Third charge = 2q
We need to calculate the electrostatic force on charge q₁ due to q₂
Using formula of electrostatic force
When placed another charge q₃ at certain distance from origin, then the net force on charge q₁ due to both charges is
The net electrostatic force on the charge at the origin doubles.
Put the value into the formula
Hence, The third charge placed is 0.80 m from origin in x-axis.
Answer:
The toy's energy is 18 J.
Explanation:
We have, a 4 kg toy is lifted off the ground and falls at 3 m/s. It is required to find toy's energy.
The toy will have kinetic energy due to its motion. The energy is given by :
So, the toy's energy is 18 J.
Answer:
The objects were 1.8m apart.
Explanation:
We will start stating the Coulomb's Law. It says that:
Where F_e is the electric force between the objects, q_1 and q_2 are the magnitude of the charge of the objects, r is the distance between them and K is the Coulomb's constant ( in vacuum). Solving for the distance r we have:
Plugging the given values into this equation, we obtain:
In words, the two charged objects were 1.8m apart.
