PHXI04:MOTION IN A PLANE

361768 The vectors \(\overrightarrow A ,\overrightarrow B \) and \(\overrightarrow C \) are such that \(|\overrightarrow A | = |\vec B|,|\vec C| = \sqrt 2 |\overrightarrow A |\) and \(\overrightarrow A + \vec B + \vec C = 0.\) The angle (in degrees) between \(\vec{B}\) and \(\vec{C}\) is

1 \(125^\circ \)
2 \(150^\circ \)
3 \(175^\circ \)
4 \(135^\circ \)
