Answer- (*u cos(theta) )/k=200m*

9Q---------q--------16Q if the distance between 9Q &16Q is d.

what is the value of q and where we have to place this charge such that all the 3 charges will be in equilibrium?

what is the value of q and where we have to place this charge such that all the 3 charges will be in equilibrium?

Solution please

Ans 18/11

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.

Pls solve

A liquid does not wet the sides of a solid, if the angle of contact Select one:

acute

Zero

Obtuse

The liquid which do not wet the solid have obtuse angle of contact. For mercury and glass, the angle of contact is .

The correct answer is: Obtuse

Sir my problem is

If two equal and opposite charges placed at a distance 2m apart then where should be the third charge placed so that three charges stay equilibrium. Plz sir tell

What is the actual colour of an object if it looks red when seen through a piece of red glass?

in a cyclotron, charge moves from one dee to another but both dees being metallic have no electric field in them. Since charge is moved by electric field but if the electric field is present it might enter the dee and thus it would contradict the statement.

Please resolve my query.

So how does charge move
