Question

An aeroplane is flying from city A to B along path 1. The path 1 is a circular arc whose centre coincides with the centre of the earth. Another aeroplane is flying along path 2 from A to B. The path 2 is circular arc whose centre is at C. O is the centre of the earth. Then,

• A. The distance travelled by $1^{st}$ aeroplane is greater than that of $2^{nd}$ aeroplane
• B. The distance travelled by $1^{st}$ aeroplane is less than that of $2^{nd}$ aeroplane
• C. The displacement of both aeroplane is different
• D. None of these

Answer 1

The correct option is A The distance travelled by $1^{st}$ aeroplane is greater than that of $2^{nd}$ aeroplane

Distance travel = path length
Fro m above diagram: A1B < A2B

$\therefore$ The distance travelled by 1st aeroplane is greater than that of 2nd aeroplane
