A particle moving in a magnetic field has increase in its velocity then its radius of the circle

A body moves a distance of 10 m along a straight line under the action of a force of 5 Newtons, if the work done is 25 joules the angle which the force takes with the direction of motion of the body is:

Planck's constant has the dimensions of:

Two forces are acting together on an object. The magnitude of their resultant is minimum when the angle between the force is.

When a Na ion and a CI ion are placed in air a force F acts between them when they are separated by a distance of 1 cm from each other the permittivity of air and the dielectric constant of water are ε₀ and K respectively When a piece of salt is placed in water then the force between Na⁺ and CI^- ions separated by a distance of 1 cm will be
