Answer:
0 N
Explanation:
because he is taller and more mass he never go back
(if it's frictionless the length doesn't even matter :) )
It would have the same kinetic energy down as the potential energy up. That is,
or
(the mass doesn't even matter). The result is
, so only the height matters really. It is almost 9 (it is
).
Answer:
the force experienced by both particles will be of same magnitude as the magnitude of charge is same for both particles but with different sign, the acceleration of both particles will be same in magnitude but opposite in direction, the direction of free electron will be opposite to the direction of electric field whereas the direction of proton will be in the direction of electric field,
Explanation:
the force experienced by both particles can be calculated by the formula
F=|q|E
the acceleration can be calculated by Newton's 2nd law i.e F=ma
the direction of electric field is always towards the positive charge so proton will be directed towards electric field and free electron will be directed away from the electric field.
Any vector which is made in x-y plane will have some angle with the x axis
in that case we can say that
also for Y direction we can say
so here the two components of vector is given by Px and Py
so we can say that
so correct answer would be
<em>Vectors Px and Py are components of vector P.</em>
