Question

A particle starts at the point (-2 0) moves along the x-axis to (2 0) find displacement

Answer 1

HEY THERE ..!!

HERE IS YOURS ANSWER;

# Method 1) ☺️

◆ Let the particle starts from (-2,0) & ends at (2,0) be represented as -2i ^ & 2i^ respectively.


So,

Displacement = Final - Initial

=> 2i^ - (-2i^) = d (vector)

=> 2i^ + 2i^ = d (vector)

=> 4i^ = Displacement vector

=> 4 units = Displacement

# Method 2) ☺️

Use the graphical method.

Make the co - ordinates on the graph paper;
(-2,0) & (2,0)

So,

Displacement = Final - Inital

Count the units or distance between the given points. That will be yours answer.
