Explain. a) Random error b) vector angle c) Personal error.
Answers
Answer: (a )- Random errors are errors made by the person carrying out the measuring, and are usually down to timing incorrectly, or reading the instrument incorrectly. It is important to try to reduce or limit the effect of random errors in measuring. Reaction time errors and parallax errors are examples of random errors.

(B)- “Angle between two vectors is the shortest angle at which any of the two vectors is rotated about the other vector such that both of the vectors have the same direction.”

(c)- An error that comes into play because of a faulty procedure adopted by the observer is called "PERSONAL ERROR". The Personal error comes into existence due to making an error in reading a scale. It is due to the faulty procedure adopted by the person making measurement.
