Question

✌️hey friends...

my question is in the attachment ....
please answer....

Answer 1

Hey Mate...

For example

I hope it is helpful for you...

Example -

Two bodies of mass 1 kg and 3 kg have positive vectors i + 2j + k and -3i -2j + k respectively. The centre of mass of this system has a position vector:

Correct Answer:

-2i – j + k

Explanation:

The position vector of other center of mass of two particle system is given by

R⃗ = m₁R⃗₁ + m₂R⃗₂ / (m₁ + m₂)

= 1/4 [-8i -4j + 4k] = -2i -j + k

Thank you...
