A stationary bomb explodes into three fragments. If the linear momentum of two A pieces are `4hati` and `3hatJ` unit respectively, then what is the value of the third fragment ?

7 unit

`sqrt(13)` unit

5 unit

6 unit

Text Solution

Verified by Experts

The correct Answer is:

`:. , p= sqrt(p_(1)^(2) + p_(2)^(2)) = sqrt(4hat(i)^(2) + 3hat(j)^(2))`
`:. , p= sqrt(16+9) = sqrt(25) = 5 units`
