Two particles of equal mass have co-ordinates
(2m, 4m, 6m) and (6m, 2m, 8m). Of these one particle has a velocity\(\vec{v}_{1}=(2 \hat{i})\) m/s and another particle has velocity \(\vec{v}_{2}=(2 \hat{j})\)m/s at time t = 0 . The coordinate of their centre of mass at time t = 1s will be :
(2m, 4m, 6m) and (6m, 2m, 8m). Of these one particle has a velocity\(\vec{v}_{1}=(2 \hat{i})\) m/s and another particle has velocity \(\vec{v}_{2}=(2 \hat{j})\)m/s at time t = 0 . The coordinate of their centre of mass at time t = 1s will be :
- (4m, 4m, 7m)
- (5m, 4m, 7m)
- (2m, 4m, 6m)
- (4m, 5m, 4m)
Answer
(B) (5m, 4m, 7m)
