An angry soccer player uses dynamite to blow the rival teams stadium apart after a close loss. Debris from the explosion flies off in all directions and is later found at distances as far as 50 m from the explosion. Estimate the maximum speed at which debris was blown outward by the explosion.

The maximum speed is  

Explanation:

From the question we are told that

   The distance covered by the debris is

The maximum range of the debris projectile is mathematically represented as

At maximum  

Now making u which is the maximum speed at which debris was blown outward by the explosion.

  we  have

substituting values

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

well clustered together.
