The greatest and least resultant of two forces acting at a point are 29 Kg wt. and 5, Kg wt. respectively. If each force is increased by 3 Kg w t the magnitude of the resultant of hew forces acting at right angles to each other is.

Question

The greatest and least resultant of two forces acting at a point are 29 Kg wt. and 5, Kg wt. respectively. If each force is increased by 3 Kg w t the magnitude of the resultant of hew forces acting at right angles to each other is. (A) 45 kg wt. (B) 35 kg wt. (C) 25 kg wt (D) 15 kg wt

a + b = 29; a - b = 5 ⇒ a = 17 , b = 12 a' = 20, b' = 15 R'= √202 + 152

Q. The greatest and least resultant of two forces acting at a point are 29 Kg wt. and 5, Kg wt. respectively. If each force is increased by 3 Kg w t the magnitude of the resultant of hew forces acting at right angles to each other is.

45 kg wt.

35 kg wt.

25 kg wt

15 kg wt

a + b = 29; a - b = 5 $\Rightarrow$ a = 17 , b = 12
$a^{'} = 20, b^{'} = 15$
$R^{'} = 2 0^{2} + 1 5^{2}$
