We will have general discussion of all physics doubts here.
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).
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.
A liquid does not wet the sides of a solid, if the angle of contact Select one:
The liquid which do not wet the solid have obtuse angle of contact. For mercury and glass, the angle of contact is .
Please resolve my query.
So how does charge move
