If two forces acting at right angles have their resultant

\sqrt{10} {~kg}

. wt. and when they act at an angle of

60^{\circ}

, the resultant is

\sqrt{13} {~kg}

. wt., then the forces are

View answer and explanation

Correct option: A

3 {~kg}

. wt.,

1 {~kg}

. wt.

Option A (3 kg. wt., 1 kg. wt.) is correct because these forces satisfy the given conditions for the resultant at right angles and at 60 degrees.
