ANSWER

A farmer moves along the boundary of a square field of side 10 m in 40 second what will be the magnitude of displacement of the farmer at the end of 2 minutes 20 seconds from its initial position

Given that

The farmer covers the entire boundary of the square field in 40 seconds

Find out

The magnitude of displacement of the farmer at the end of 2 minutes 20 seconds from his initial position

Solution

The total distance travelled by the farmer in 40 seconds is 4*(10) = 40 meters.

Therefore, the average distance covered by the farmer in one second is: 40m/40 = 1m

Two minutes and 20 seconds can be written as (2 x 60) + 20=140 seconds.

The total distance travelled by the farmer in this timeframe is: 1 m * 140 = 140m

Since the farmer is moving along the boundary of the square field, the total number of laps completed by the farmer will be: 140m/40 = 3.5 laps

Now, the total displacement of the farmer depends on the initial position. If the initial position of the farmer is at one corner of the field, the terminal position would be at the opposite corner (since the field is square).

Hence here, in this case, the total displacement of the farmer will be equal to the length of the diagonal line across the opposite corners of the square.

On applying the Pythagoras theorem,

The length of the diagonal is given as:

√(102+102)= √200= 14.14m.

This is the maximum possible displacement of the farmer.

If the initial position of the farmer is at the mid-point between two adjacent corners of the square, the net displacement of the farmer would be equal to the side of the square, which is 10m. This is the minimum displacement.

When the farmer starts at a random point around the perimeter of the square, his net displacement after travelling 140m will lie between 10m and 14.14m.

Gravitation	Gravity
It can be an attraction force or repulsive force	It is always an attraction force
It is an universal force	It is not an universal force
It is a weak force	It is a strong force
The force is <nobr>F=(GM₁M₂)/R²</nobr> (G= gravitational constant)	The force is F=mg (g=acceleration due to gravity)
The direction of gravitational force lies in the radial direction from the masses	The direction of force of gravity is along the line joining the earth’s center and the center of the body. Its direction is towards the center of the earth.
Gravitation force is a vector quantity	Gravity is a vector field
The force can be 0 when separation between bodies is infinity	The force of gravity can be 0 at the center of the earth
It requires two masses	It requires only one mass
