[pink_ele]

Q 5 Match the column
If net force on a system of particles is zero then
Table 1 Table 2

a) acc. of COM p) constant

b)momentum of COM q)zero

c)velocity of COM r) may be zero

d)velocity of individual particles s) may be constant

Ans is 5>a - pq, b - pr, c-pr, d-rs

 

[Shooting Star]

Ans is 5>a - pq, b - pr, c-pr, d-rs

a - pq is not correct.

Can you match more than two on the right with one on the left?
