A particle has two equal accelerations in two given directions. If one of the accelerations is halved, then the angle which the resultant makes with the other is also halved. The angle between the accelerations is

View answer and explanation

Correct option: A

120^{\circ}

Option A (

120^{\circ}

) is correct because the given condition about halving one acceleration and the resultant angle leads to the equation

\cos \theta = -1/2

, which gives

\theta = 120^{\circ}
