1) find speed (8.8 m/s)
2) find acceleration (38.7 m/s^2)
answer is about 38.7 m/s^2
I would think the answer is c.
Answer:
Explanation:
It is given that,
The radius of the solid sphere, R = 50 cm = 0.5 m
Charge on the sphere, 
We need to find the magnitude of the electric field r = 10.0 cm away from the center of the sphere. The electric field at point r away form the center of the sphere is given by :



So, the electric field 10.0 cm away from the center of the sphere is
. Hence, this is the required solution.
I'm thinking the answer is going to b B
