- According to Law of Triangle of Forces
- Periodic time of body moving with simple harmonic motion, is
- The height at which the end of a rope of length ‘l’ should be tied so that a man pulling at the other end may have the greatest tendency to overturn the pillar, is
- The ratio of the ranges on the inclined plane with motion upward and with motion downward for a given velocity, angle of projection will be
-
The C.G. of the shaded area of the bellow figure from the x-axis is
- The velocity of a body fallen from height ‘h’, on reaching the ground is given by
- The C.G. of a right circular cone lies on its axis of symmetry at a height of
- Centre of gravity of a thin hollow cone lies on the axis of symmetry at a height of
- The apparent weight of a man in a moving lift is less than his real weight when it is going down with
A.
Three forces acting at a point, can be rep-resented by the sides of a triangle, each side being in proportion to the force |
B.
Three forces acting along the sides of a triangle are always in equilibrium |
C.
If three forces acting on a, point can be represented in magnitude and direction, by the sides of a triangle taken in order, these will be in equilibrium |
D.
If the forces acting on a particle be represented in magnitude and direction by the two sides of a triangle taken in order, their resultant will be represented in magnitude and direction by the third |
