Two large circular discs separated by a distance of are connected to a battery via a switch as shown in the figure Charged oil drops of density are released through a tiny hole at the center of the top disc Once some oil drops achieve terminal velocity, the switch is closed to apply a voltage of across the discs As a result, an oil drop of radius stops moving vertically and floats between the discs The number of electrons present in this oil drop is (neglect the buoyancy force, take acceleration due to gravity and charge on an electron )

A table tennis ball has radius m and mass kg. It is slowly pushed down into a swimming pool to a depth of 𝑑 = 0.7 m below the water surface and then released from rest. It emerges from the water surface at speed 𝑣, without getting wet, and rises up to a height 𝐻. Which of the following option(s) is(are) correct?[Given: , density of water = , viscosity of water = Pa-s.]
1
The work done in pushing the ball to the depth 𝑑 is 0.077 J
2
If we neglect the viscous force in water, then the speed 𝑣 = 7 m/s.
3
If we neglect the viscous force in water, then the height 𝐻 = 1.4 m.
4
The ratio of the magnitudes of the net force excluding the viscous force to the maximum viscous force in water is 500/9.
