Which statement best explains the difference between velocity and speed?
2 answers:
Explanation:
Speed : It is defined as the overall distance travelled by an object divided by total time taken. The mathematical expression is given by :
It is a scalar quantity i.e. it has only magnitude.
Velocity : It is defined as the total displacement (D) of the particle divided by total time taken. It can be given by :
It is a vector quantity. It have both magnitude and direction.
Out of given options, the statement that best explains the difference between velocity and speed is (B) i.e. "Velocity is a vector and requires a direction to completely describe it".

<h3>What is the Electric field?</h3>Generally, the equation for the electric field uniform charged is mathematically given as
Therefore
E=lr/3E0=3Ee0/r
Therefore
E=3*6*10^4*8.85*10^{-12}
E=19.9*10^{-5}c/m^3
In conclusion, E=19.9*10^{-5}c/m^3
E=19.9*10^{-5}c/m^3
