Problem solving tricks-Right hand rules (Magnetic fields due to currents)

Right hand rule for cross product:-
Consider that c is the cross product of two vectors a and b i.e.,
c=a x b
If direction of vector a is along the x axis and that of b along z axis then direction of vector c could be find using right hand rule for cross products.

Overview of electrostatics and electricity

Overview of electrostatics and electricity Electrostatics involves electric charges namely positive and negative charges, the forces between them which is known as electric force , the field that surrounds them, and their behavior in materials. Coulumb’s law is the simple relation that governs electrostatic interactions and the field around the charges is described using the concept of electric field. Coulumb’s law is a inverse square … Continue reading Overview of electrostatics and electricity »

Nuclear Force – Definition | properties of Nuclear Force

We already know about gravitational and electrostatic forces now a question arises that does these forces still hold when we talk about nuclear dimensions as gravitational force between two protons is far too less to hold them and electrostatic force between two protons always a force repulsive in nature . So what hold protons together to form a nucleus.
