Is it possible for the electric field between two positive charges to equal zero along the line joining the two charges?
1 answer:
Answer:
Yes electric field between the line joining may be zero when both the charges are of opposite magnitude
Explanation:
Electric field due to a point charge is given by
From the relation of magnitude of electric field we can see that magnitude of electric field depends upon the m,magnitude of charge and distance between them
So electric field between the line joining may be zero when both charges are of opposite magnitude ( Means if one charge is positive then other is negative )

Answer:
Explanation:
This is a projectile motion problem. We will first separate the motion into x- and y-components, apply the equations of kinematics separately, then we will combine them to find the initial velocity.
The initial velocity is in the x-direction, and there is no acceleration in the x-direction.
On the other hand, there no initial velocity in the y-component, so the arrow is basically in free-fall.
Applying the equations of kinematics in the x-direction gives
For the y-direction gives
Combining both equation yields the y_component of the final velocity
Since we know the angle between the x- and y-components of the final velocity, which is 180° - 2.8° = 177.2°, we can calculate the initial velocity.
