A charge `6 muC` is placed at the origin and another charge `-5 muC` is placed on the Y-axis at position A(0,6,1)m:- Calculate the work done to bring a proton from infinity to the point P.

A charge 6 mu C is placed at the origin and another charge -5 mu C is placed on the y axis at a position A (0, 6.0) m. Calculate the work done to bring a proton from infinity to the point P ? What is the significance of the negative sign ?

A charge 6 muC is placed at the origin and another charge -5 muC is placed on the Y-axis at position A(0,6,0)m. Calculate the total electric potential at the point P whose coordinates are (8, 0, 0) m.

Potential at a point A in space is given as 4 xx 10^5V :- Find the work done in bringing a charge of 3muC from infinity to the point A.

Two point charges + 0.2muC and 0.01muC are placed 10cm apart. Calculate the work done in reducing the distance 5cm between them.

A force vec((F)) = - K(yhat(i) + x hat(j)) (where K is a positive constant) acts on a particle moving in the X-Y plane. Starting from the origin, the particle is taken along the positive X-axis to the point (a, 0) and then parallel to the Y-axis to the point (a,a). The total work done by the force vec(F) . of the particle is

Two positive charges of 20 mu C and 8 mu C are 20 cm apart, find the work done in bringing them 5 cm closer

What charge placed 9 cm from a charge of 100 muC will produce a force of 1//9 N in air?

The length of a straight thin wire is 2 m. It is uniformly charged with a positive charge of 3 C. If charge density of the wire is 1.5 x 10-6 C/m then calculate the electric intensity due to the wire at a point 1.5 m away from the centre of the wire.
