Concept explainers
Length of the vector.
Answer to Problem 90A
Length of vector is 10mm to represent velocity of 20 m/sec.
Explanation of Solution
Given:
15 mm long vector represent a velocity of 30 m/sec
Formula used:
If the length of vector is directly proportional to velocity.Then the relation between length and velocity will be,
Calculation:
Here,
Now, putting the value of
Conclusion:
Therefore, length of vector is 10 mm to represent velocity of 20 m/sec.
