There are six points in a plane. The largest distence between two points is D and smallest distence is d. Find the ratio D/d.
A circular ring of radius r made of a nonconducting material is placed with its axis is parallel to a uniform electric field if the ring rotated by 180 degrees Does the flux changes? A Q charge is uniformly distributed on a thin spherical shell If a point charge is brought near it what is […]
Sarin John Skaria Asked: “We know that a kidney stone is broken down by using ultrasound waves.now think about creating a machine which can produce a large no.of ultrasound waves in an instance . it will be useful for us to create a tunnel under a hill,for digging a hole in the ground rapidly.”
In a single fixed pulley the velocity ratio is always more than mechanical advantage. Why?
Why the magnetic field lines do not intersect How contact force is related with physical pendulum?
TWO IDENTICAL CONDUCTING SPHERES ‘A’ & ‘B’ CARRY EQUAL CHARGES. THEY ARE INITIALLY SEPARATED BY A DISTANCE MUCH LARGER THAN THEIR DIAMETERS AND THE FORCE BETWEEN THEM IS ‘F’. A THIRD IDENTICAL CONDUCTING SPHERE ‘C’ IS UNCHARGED. SPHERE ‘C’ IS FIRST TOUCHED TO ‘A’ AND THEN TOUCHED TO ‘B’ AND THEN REMOVED. AS A RESULT, […]
A thermo stated chamber at a height ‘h’ above the earth’s surface and maintained at 30 degree Celsius has a clock fitted with an uncompensated pendulum. The maker of the clock for the chamber mistakely designed it to maintain correct time at 20 degree Celsius. It is found that if the chamber were brought to […]
