Answer:
=
Explanation:
Given :
the distance between the two wires is = 2 cm
= 0.02 m
Current in one of the wire, I = 25 A
Now we know that, when the direction of the current is same that is in one direction , the magnetic field at the mid point in between the two wires will oppose each other.
Therefore we know that
= 
=
= 
The incline is frictionless, this means we can use the conservation of energy: the initial kinetic energy of the block

is converted into gravitational potential energy

where h is the height reached by the block as it stops. By equalizing the two formulas, we get


However, this is the maximum height reached by the block. The distance along the surface of the plane is given by:
The answer to the given question above would be ZERO. For general projectile motion, the one that best describes the horizontal component of a projectile's velocity is this: <span>The horizontal component of a projectile's acceleration is zero. Hope this answers your question.</span>
