a) Product of force & perpendicular distance
b) Product of mass & acceleration
c) Product of force & mass
d) Product of force & acceleration.
Ans (a)
3) The moment of force is
a) Scalar quantity b) vector quantity c) Both (a) & (b) d) None of this
Ans (b)
4) By The algebraic sum of forces consisting the couple is
a) one
b) b) zero
c) two
d) none of this
Ans (b)
5) A body is in equilibrium if
a) All force acting” on body in apposite direction
B) All force acting on body in same direction
C) All the force acting on body is zero.
d) Both (a) & (c)
Ans (c)
6) The force of 20N is applied at distance of 40cm from the axis. The moment of force is
a) 8 Nm
b) 0.4 Nm
c) 8.5 Nm
d) 20 Nm
Ans (a) moment of force = fx d
where f=20N, d = 40cm = 0.4m
: momentum of force = 20×0.4 = 8 Nm

a) 3m b) 0.35m c) 5m d) 3.5m
Ans. (d)
moment of force: f x d
7 = 2d
7/2 = d
3.5m = d

Ans (a)
10) The Point at which entire weight of body concentrated.
a) centre of gravity
b) end point
c) centriod
d) central point
Ans (a).
11) In uniform circular motion the body moves with
a) constant acceleration.
b) constant speed.
c) changing speed
d) None of these
Ans (b)
