Two equally charged spheres of mass 1.0 g are placed 2.0 cm apart. when released, they begin to accelerate at 980 m/s2. what is the magnitude of the charge on each sphere? two equally charged spheres of mass 1.0 g are placed 2.0 cm apart. when released, they begin to accelerate at 980 m/s2. what is the magnitude of the charge on each sphere? 210 nc 120 nc 180 nc 150 nc

210nC

Explanation:

The force experimented by two charges and separated a distance is given by Coulomb's Law:

where is the Coulomb constant.

The acceleration experimented by any (both) of them will be given by Newton's 2nd Law: F=ma

Combining both equations and considering that , we get:

Which means:

Which for our values is:

Which is very close to the option 210nC
