Answer:
4 m/s
Explanation:
Momentum is defined as:
where
m is the mass of the object
v is its velocity
For the object in this problem, we know:
p = 200 kg m/s is the momentum
m = 50 kg is the mass
Solving for the velocity, we find:
A particle with charge Q and mass M has instantaneous speed u1 when it is at a position where the electric potential is V1. At a

The distance is
Explanation:
From the question we are told that
The wavelength of the light is
The distance between the slit is
The between the first and second dark fringes is
Generally fringe width is mathematically represented as
Where D is the distance of the slit to the screen
Hence
substituting values
