OT = 2.4M
In ΔOTQ
OQ2 = OT2 + TQ2 ⇒ TQ2 = OQ2 - OT2
= (5)2 - (2.4)2

Let C be a circle of radius 5 meters having center at O. Let PQ be a c...
Given:
- Circle C has a radius of 5 meters and its center is at point O.
- Chord PQ passes through points A and B.
- Point A is located 4 meters north of O.
- Point B is located 3 meters east of O.

To find:
The length of chord PQ.

Solution:
Step 1: Calculate the length of AO and BO
Using Pythagoras theorem, we can find the length of AO and BO.

Length of AO = √(radius^2 - distance^2) = √(5^2 - 4^2) = √(25 - 16) = √9 = 3 meters

Length of BO = √(radius^2 - distance^2) = √(5^2 - 3^2) = √(25 - 9) = √16 = 4 meters

Step 2: Calculate the length of AB
Using the distance formula, we can find the length of AB.

Length of AB = √((x2 - x1)^2 + (y2 - y1)^2) = √((3 - 0)^2 + (4 - 0)^2) = √(3^2 + 4^2) = √(9 + 16) = √25 = 5 meters

Step 3: Calculate the length of PQ
Since PQ is a chord passing through the center of the circle, it bisects AB.

Length of PQ = (Length of AB)/2 = 5/2 = 2.5 meters

However, we are looking for the nearest whole number, so we round up to the nearest whole number.

Length of PQ (rounded up) = 3 meters

Conclusion:
The length of chord PQ is nearest to 3 meters. Therefore, the correct option is D.
