A charged particle is suspended in equilibrium in a uniform vertical electric field of intensity 20000 V/m. If mass of the particle is 9.6 × 10^–16 C, 3 kg, the charge on it and excess number of electrons on the particle are respectively (g = 10 m/s²)

Four charges +Q, – Q, + Q, – Q are placed at the corners of a square taken in order. At the centre of the square

Top of the stratosphere has an electric field E (in units of V/m) nearly equal to

Charge q, 2q, 3q and 4q are placed at the corners A, B, C and D of a square as shown in the following figure. The direction of electric field at the centre of the square is along

Point charges q₁ = 2 µC and q₂ = –1 µC are kept at points x = 0 and x = 6 respectively. Electrical potential will be zero at points

Equipotential surfaces associated with an electric field which is increasing in magnitude along the x-direction are

A bullet fo mass 2 gm is having a charge of 2µC. Through what potential difference must it be accelerated, starting from rest, to acquire a speed of 10 m/s

The points resembling equal potentials are

Figure shows three points A, B and C in a region of uniform electric field E ⃗. The line AB is perpendicular and BC is parallel to the field lines. Then which of the following holds good. Where V_A,V_Band V_C represent the electric potential at points A, B and C respectively

In a certain charge distribution, all points having zero potential can be joined by a circle S. Points inside S have positive potential and points outside S have negative potential. A positive charge, which is free tomove, is placed inside S
