1. The unit of force in S.1. system of units is :

(^) Dyne . (B) Kilogram
(C) Newton (D) Watt
2, One kg force is equal to :
(ക 98N (B) 78N
(¢) 89% (D) 12N
8. The angle between two forces when the resultant is maximum and minimum respectively
வு:
(A) 180" ೩೧6 0* (1) 0" 876 1805
(0) 80* ന 180 (2) 90° and 0°

4. [If the resultant of two equal forces has the same magnitude as either of the forces, the angle
between the two forces is :
@ 30 (ए) 60
©) 90 യ) 1805

5. The resultant of the two forces P and © 15 R. If Q is doubled, the new resultant is
perpendicular to P. Then :
@) ۶-۹ ® Q=R
(ட ‏7ھ‎ (D) None of these

6. സസ forces are acting at an angle of 120°. The bigger force is 40 N and the resultant is
perpendicular to the smaller one. The smaller force is :

(^) 20N (0) 40N
(0 80%! (D) None of these
7. Concurrent forces are those forees whose lines of action :
(A) Lie on the same line . (ए) Meet at one point
(0 Meet on the same plane (D) None of these

8. A number of forces acting at a point will be in equilibrium, 1:
(ക All the forces are equally inclined
(B) Sum of all the forces is zero
(C) Sum of resolved parts in the vertical direction and horizontal direction is zero
(0) All the forces are equally perpendicular
