Two objects 2 kg and 6 kg are placed.
Where, 2 kg in left.
If 6 kg moves 2 meter towards right then by what distance does 2 kg should move that centre of mass will remain at its initial position.
Answers
Answer:
In order to solve this type of question, let is consider the centre of mass of the 2 particle system to be located at origin (0,0)
Now, the shift should be such that the centre of mass be still at origin.
Let change in position of 2kg be ∆x1 and Chang in position of 6 kg be ∆x2.
Using the formula for centre of mass calculation:
(m1 *∆x1 + m2*∆x2)/(m1 +m2) = 0
=> 2 *∆x1 + 6*2 = 0
=> ∆x1 = -6 metres.
negative sign indicates that 2 kg has to moved to opposite direction as that of 6kg.
The answer is 6 metres to the left.
Explanation:
Answer:
We using formula for centre of Calculating Mass .
(m1 × /\x1 + m2 × /\x2 )/(m1 + m2 ) = 0 .
= 2×/\x1 + 6×2 = 0 .
= /\x1 = - 6 metres .
if 2 kg is moved in the size of -6 KG so it can be 6 kg .
Answer : 6 metre to left .
