It will travel slowest through gases.
Answer:2.67kgm/s cube
Explanation: density = mass ÷ volume = 400 ÷ 150
Answer:

Explanation:
Given:
Force between pair of charges= 900 newtons
The distance between the charges = 0.01 meters
Strength of Charge first q1 = 2e-10 Coulomb
To find:
Strength of Charge second q2 = ____ Coulomb?
Solution:
We know that,
Force between two charges separate by distance r is given by the equation,
