What is the distance between two spheres, each with a charge of 2.4×10^-6 C, when the force between them in 0.50 N?

Use the formula F= k q1q2/r^2 where k= 1/4π€ and it's value in air is 9× 10^9.

q1=q2= 2.4×10^-6C

F= 0.5N

You will get the value of r^2 and then will have to find the squre root of that value.

Explanation:

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
