Answer:
The new force becomes 4 times the initial force.
Explanation:
The force of attraction or repulsion is given by the relation as follows :
Where
d is the distance between the interacting charges
F is inversely proportional to the distance between charges.
If the distance is halved, d'=(d/2), new force is given by :
So, the new force becomes 4 times the initial force.
- Height=h=500m
- Acceleration=g=10m/s^2
- Initial velocity=u=0
- Speed of sound=c=340m/s
- TIME TAKEN BY STONE TO HIT WATER=t
- Time taken by sound to hear back=T
