Question

A particle, at first moves 4m in south-west direction, then 5m in East and then it move 6m in north by acquiring an angle 60° with east. Find the displacement.
​

Answer 1

Explanation:

i guess it would be 0 not sure

Answer 2

Answer:

Given

A particle, at first moves 4m in south-west direction, then 5m in East and then it move 6m

Explanation:

To Find:-

Net Displacement from starting point.

Calculation:-

We will apply vector to solve these kind off question.

When particle moves 4m south

:· r 1 = 4(–j)

When particle moves 5m east

:· r 2= 5 i

When particle moves 6m at (60°)

:· r 3= 3 i + 3 √3i

Now Net Displacement

r= r1 + r2 + r3

:· r = 4( j) + ( 5i + 3i) + 3√3i
