Two conducting spheres, one with radius 2.00 × 101 cm, the other with radius 8.00 cm, are placed next to each other such that their surfaces are a distance 1.00 × 10−1 m apart. both spheres have a mass of1.00 × 101 mg and the net charge on the two spheres is 7.00 × 101 μc. the 2.00 × 101 cm sphere exerts a 6.23 × 104 mn force on the 8.00 cm sphere.
assuming that both spheres are negatively charged, how many excess electrons are on the sphere with the greatest charge magnitude?

Gravity bc it’s gravity

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

'b ' is the correct conclusion.
