MCQs-PYQs-12th-jee

A given charge is situated at a certain distance from an electric dipole in the end-on position experiences a force F. If the distance of the charge is doubled, the force acting on the charge will be

MCQs-PYQs-12th-jee

In Millikan’s oil drop experiment an oil drop carrying a charge Q is held stationary by a potential difference 2400V between the plates. To keep a drop of half the radius stationary the potential difference had to be made 600V. What is the charge on the second drop

MCQs-PYQs-12th-jee

Two equal negative charges -q is fixed at points (0, a) and (0, -a) on the Y-axis. A positive charge ‘q’ is released from rest at the point (x greater than a) on the x-axis. What is the frequency of motion

MCQs-PYQs-12th-jee

Two-point charges (+Q) and (-2Q) are fixed on the X-axis at positions a and 2a from origin respectively. At what positions on the axis, the resultant electric field is zero

MCQs-PYQs-12th-jee

An infinite number of electric charges each equal to 5 nano- coulomb (magnitude) are placed along X-axis at x = 1cm, x = 2 cm, x = 4 cm x = 8 cm and so on. In the setup if the consecutive charges have opposite sign, then the electric field in Newton/Coulomb at x = 0 is

An electron is released from the bottom plate A as shown in the figure (E = 10⁴ N/C). The velocity of the electron when it reaches plate B will be nearly equal toAn electron is released from the bottom plate A as shown in the figure (E = 10⁴ N/C). The velocity of the electron when it reaches plate B will be nearly equal to

MCQs-PYQs-12th-jee

Two charges each equal to ηq ( η⁻¹ less than √ 3 ) are placed at the corners of an equilateral triangle of side a. The electric field at the third corner is E₃ where ( E₀ = q / 4π ε₀ a² )

MCQs-PYQs-12th-jee

The distance between charges 5×10⁻¹¹C and -2.7×10⁻¹¹C is 0.2 m. The distance at which a third charge should be placed in order that it will not experience any force along the line joining the two charges is

MCQs-PYQs-12th-jee

An -particle of mass 6.4×10⁻²⁷ kg and charge 3.2×10⁻¹⁹C is situated in a uniform electric field of 1.6×10⁵ Vm¯¹. The velocity of the particle at the end of -1 2×10² m path when it starts from rest is

MCQs-PYQs-12th-jee

A rod lies along the x-axis with one end at the origin and the other at x→∞. It carries a uniform charge λC/m. The electric field at the point x = -a on the axis will be
