A bomb initially at rest explodes by it self into
P three equal mass fragments. The velocities of two

W fragments are \( (3 \hat{\mathrm{i}}+2 \hat{\mathrm{j}}) \mathrm{m} / \mathrm{s} \) and \( (-\hat{\mathrm{i}}-4 \hat{\mathrm{j}}) \mathrm{m} / \mathrm{s} \).
The velocity of the third fragment is (in \( \mathrm{m} / \mathrm{s} \) )-
(1) \( 2 \hat{i}+2 \hat{j} \)
(2) \( 2 \hat{i}-2 \hat{j} \)
(3) \( -2 \hat{i}+2 \hat{j} \)
(4) \( -2 \hat{i}-2 \hat{j} \)
