Answer:

Explanation:
There are two spheres name 1 and 2 and they posses the same charge, which is +q.
And they have equal mass which is 2.098 g.
The distance between these two spheres is,
.
And the acceleration of each sphere is,
.
Now the coulumbian force experience by 1 sphere due to 2 sphere,
.
And also the newton force will occur due to this force,
.
Now equate the above two values of force will get,

Further solve this,
.
Substitute all the known variables in above equation,
.
.
