Answer:
Explanation:
From the question we are told that
Initial velocity of 60 m/s
Wind speed
Generally Resolving vector mathematically
Generally the equation Pythagoras theorem is given mathematically by
Therefore Resultant velocity (m/s)
b)Resultant direction
Generally the equation for solving Resultant direction
Therefore
Answer 1) The electric field at distance r from the thread is radial and has magnitude
E = λ / (2 π ε° r)
The electric field from the point charge usually is observed to follow coulomb's law:
E = Q / (4 π ε° )
Now, adding the two field vectors:
= {2.5 / (22 π ε° X 0.07 ) ; 0}
Answer 2) = {2.3 / (4 2 π ε°) ( - 7/ (√(84); -12 / (√84))
Adding these two vectors will give the length which is magnitude of the combined field.
The y-component / x-component gives the tangent of the angle with the positive x-axes.
