a boy travels 5 km towards east and then 3 km towards north find the distance travelled and displacement
Answers
To find the displacement we should be careful about the direction as well. Displacement measures the position of the car with respect to initial position. From the figure, it can be easily observed that the car is 2KM west from the starting point.
Displacement = +3KM + (- 5KM)
= -2KM (2KM west)
Here -ve sign represents west direction.
To find magnitude, it's just number without caring direction. Therefore,
The magnitude of displacement = 2KM
Answer:
Rational number, in arithmetic, a number that can be represented as the quotient p/q of two integers such that q ≠ 0. In addition to all the fractions, the set of rational numbers includes all the integers, each of which can be written as a quotient with the integer as the numerator and 1 as the denominator
