A 6 kg bomb at rest explodes into three equal pieces P, Q and R. If P flies with speed 30 m/s and Q with speed 40 m/s making an angle `90^(@)` with the direction of P. The angle between the direction of motion of P and R is about

Find the angle between the lines whose direction ratios are p, q, r and q-r, r-p, p-q

The resultant of two forces P and Q makes an angle of 30^(@) with P. What is the angle between P and Q, if the magnitude of the resultant is equal to Q sqrt(3) ?

Two moving particles P and Q are 10 m apart at a certain instatn. The velocity of P is 8 m/sm making an angle of 30^(@) with the line joining P abd Q and that of Q is 6m/s making an angle 30^(@) with PQ as shwon in figure. Then, angular velocity of P wiht respect to Q is

A particle slides with a speed of 3m s^(-1) at P. When it reaches Q ,it acquires a speed of 4m s^(-1) after describing an angle of 60^(@) at O as shown in figure .Find the changes in the velocity of the particle between P and Q . Assume that the path followed by the particle is circular from P to Q
