Answer:
Explanation: according to Coulomb's inverse-square law is proportional to the square of distance between them and is given by

where r is the distance between the charges & k is the Coulomb's constant
k=1/(4*ε_0*π)
k=9*10^9
the distance between the charges in this question is d_1
hence the magnitude of the force exerted by q_0 on q_1 is given by

due to location of particle 1 above the particle 0 the direction of force is parallel to y axis and in vector form

We will all chaotically burn to death!

It condenses into liquid water.
No they are not the same material because having the same density doesnt mean its the same material also they can have a different density and be the same material
