PhysicsMediummultiple choice

A particle is shifted from A to B and then from B to C where $A, B$ and C are the midpoints of the corresponding faces of a cube of side 2m. If a force $F = (3 \hat{i} + 4 \hat{j} - 5 \hat{k}) N$ is continuously acting on the particle, then select correct alternative is

Options:(select one or more)

Answer:

A, B, C, D

Solution:

$OA = \hat{i} + \hat{k}, OB = 2 \hat{i} + \hat{j} + \hat{k}, OC = \hat{i} + 2 \hat{j} + \hat{k}$

$\Rightarrow AB = OB - OA = \hat{i} + \hat{j}, BC = OC - OB = \hat{j} - \hat{i}, AC = OC - OA = 2 \hat{j}$
