1.	If `a_(r )` and `a_(t)` respresent radial and tangential acceleration, the motion of a particle will be circualr isA. `a_(r) = 0` and `a_(t) = 0`B. `a_(r) = 0` but `a_(t) != 0`C. `a_(r) != 0` and `a_(t) = 0`D. `a_(r) !=0` and `a_(t) != 0`
Answer» Correct Answer - C::D In uniform circular motion, `a_(t) = 0`, but in non uniform circular motion, `a_(t) != 0`. In both cases, `a_(r) != 0`.

What is the position vector of centre of mass of two particles of equal masses ?
Consider a two particle system with particles having masses `m_1 and m_2` if the first particle is pushed towards the centre of mass through a distance d, by what distance should the second particle is moved, so as to keep the center of mass at the same position?A. `d`B. `(m_(2)//m_(1))d`C. `[m_(1)//(m_(1) + m_(2))]d`D. `(m_(1)//m_(2))d`

As shown in Fig. the two sides of a step ladder `BA` and `CA` are `1.6 m` long and hinged at `A`. A rope `DE, 0.5 m` is tied half way up. A weight `40 kg` is suspended from a point `F, 1.2 m` from B along the ladder` BA`. Assuming the floor to be fricionless and neglecting the weight of the ladder, find the tension in the rope and forces exerted by the floor on the ladder. (Take `g = 9.8 m//s^(2))` (Hint. Consider the eqilibrium of each side of the ladder separately.)

A dics rotates about the central axis starting from rest and accelerates with constant angular accelertion. At one time, it is rotating at `10 rps` , `60` revoluting later, its angular speed is `15rps`. Calculate (i) angular acceleration (ii) time required to complate `60` revols (iii) the time required to reach `10 rev//sec` angular speed and (iv) number of revoluting from rest until the time the disc reaches `10rps` angular speed.
A Meery -go-round, made of a ring-like plarfrom of radius `R and mass M`, is revolving with angular speed `omega`. A person of mass `M` is standing on it.
