What will be sign of the velocity of the point P^(') , which is the projection of the velocity of the reference particle P? P is moving in the circle of radius R in anticlockwise direction.

In figure, what be the sign of the velocity of the point P', which is the projection of the velocity of the reference particle P.P is moving in a circle of radius R in anti-clockwise direction.

Six equal resistances are connected between points P, Q and R as shown in the figure. Then the net resistance will be maximum between

The positon vectors of points P, Q, R are given by overline(p)=overline(a)-2overline(b)+3overline(c), overline(q)=-2overline(a)+3overline(b)+2overline(c), overline(r)=-8overline(a)+13overline(b) . If the points P, Q, R are collinear, then the ratio in which point P divides the line segment RQ is

A particle starts from point A moves along a straight line path with an acceleration given by a = p - qx where p, q are connected and x is distance from point A . The particle stops at point B. The maximum velocity of the particle is

In the following displacement (x) vs time (t) graph, at which among the point P,Q and R is the object speed increasing ?

If the centroid of the triangle formed by points P(a,b),Q(b,c) and R(c,a) is at the origin, what is the value of a+b+c?

Two particles P and Q simultaneously start moving from point A with velocities 15 m//s and 20 m//s respectively. The two particles move with acceleration equal in magnitude but opposite in direction. When P overtakes Q and B then its velocity is 30 m//s the velocity of Q at point B will be
