All protons in an atom remain packed in ...

All protons in an atom remain packed in a small nucleius inspite of the electrostatic repulsive force among them.Why?

Text Solution

Verified by Experts

There are very strong attractive nuclear forces among nucleons i.e., between proton- proton, neutron-neutron and proton-neutron. These strong, attractive nuclear forces are sufficient to overcome the electrostatic force of repulsion between protons. As a result, all the protons in an atom remain packed in a small nucleus inspite of electrostatic repulsive forces, among them.

Two insulated charged copper spheres A and B have their centres separated by a distance of 50 cm. What is the mutual force of electrostatic repulsion if the charge on each is 6.5 xx 10^-7 C ? The radii of A and B are negligible compared to the distance of separation. What is the force of repulsion if each sphere is charged double the above amount, and the distance between them is halved?

A magnetic field set up using Helmholtz coils is uniform in a small region and has a magnitude of 0.75 T. In the same region, a uniform electrostatic field is maintained in a direction normal to the common axis of the coils. A narrow beam of (single species) charged particles all accelerated through 15 kV enters this region in a direction perpendicular to both the axis of the coils and the electrostatic field. If the beam remains undeflected when the electrostatic field is 9.0 xx 10^5 V m^-1 make a simple guess as to what the beam contains. Why is the answer not unique?
