Answer:
Force,
Explanation:
Distance between proton is 0.005 m
It is required to find the force between two protons. Protons have of positive charge of . Two protons will have a force of repulsion between them. The force is given by :
So, the force between two protons is .
As ball is projected up in air at an angle of 45 degree without any air resistance
Let the initial speed will be v
now we will have
In x direction
in y direction
now displacement in x direction
displacement in y direction
now from above two equations we have
so above equation is a quadratic equation and hence it will be a parabolic curve
so correct answer will be
<em>C. parabolic curve.</em>
