Question

two particles of masses 1kg and 4kg are located at X equal to zero and X equal to 5 find the position of the centre of mass​

Answer 1

Answer:

2 m

please mark as brilliant

Answer 2

Answer:

Since, both the particles lies on x - axis, the COM will also lie on x - axis. Let the COM islocated at x= x, then

r  

1

​

 = distance of COM from the particle of mass 1 kg= x

and r  

2

​

 = distance of COM from the particle of mass 2 Kg = (3 - x)

Using

r  

2

​

 

r  

1

​

 

​

=  

m  

1

​

 

m  

2

​

 

​

 

or  

3−x

x

​

=  

1

2

​

 

or x=2m

Thus, the COM of the two particles is located at x = 2 m.
