## Physics Doubt

We will have general discussion of all physics doubts here.

### PHYSICS--VECTOR

by Sagnik Seth -The resultant R, of two forces P and Q, inclined at a fixed angle, makes an angle theta with P. Show that, the resultant of the two forces (P + R) and Q, inclined at the same angle, will make an angle theta/2 with force (P+R).

### Physics

by RISHI DAS -There is an Ā vector and a B vector as 3i-j+7k and 5i-j+9k. The direction of cosine beta of the vector A-B is .

### Current Electricity

by Sk Tg -### Electrostatics

by Saptarshi Chakraborty -Two particles X and Y, of equal mass and with unequal positive charges, are free to move and are initially far from each other. With Y at rest, X begins to move towards it with a initial velocity u. After a long time finally:

(a) X will stop, Y will move with velocity u.

(b) X and Y will both move with a velocity u/2 each.

(c) X will stop, Y will move with velocity < u.

(d) both will move with a velocity < u/2.
