Can you give more information
Answer:
B v1= 12.5m/s
Explanation:
As the acceleration is constant and time taken is also same and distance covered is halfed so the speed will also be halfed.
Explanation:
The law of repulsion is given by Coulomb. The mathematical form of Coulomb law is given by :
...............(1)
Where
F is the force
k is the electrostatic constant
are electric charges
r is the distance between charges
The Newton's law of universal gravitation is given by :
..............(2)
G is the universal gravitational constant
From equation (1) and (2) it is clear that both law obeys inverse square law and both are of same type. So, the law of repulsion by Coulomb agrees with the Newton's law of universal gravitation.
Increase in velocity and decrease in velocity are the answers
Because acceleration is just the change if it starts moving
