the sum of the forces

Lorentz Force - The force experienced by a charged particle moving in space where both electric and magnetic field exist is called lorentz force. The lorentz force is therefore the vector sum of force due to electric field and the for..

A body on which two or more forces act is said to be in equilibrium if there is no change in its state of rest or of uniform motion. The condition necessary for equilibrium is that the vector sum of forces acting on the body should be zero. i.e., This also implies that..

Coulomb's law describes only the interaction of two point charges. Experiments show that when two charges exert forces simultaneously on a third charge, the total force acting on that charge is the vector sum of the forces that the two charges would exert ind..

If a body is in equilibrium under the action of a number of forces, then the algebraic sum of the moments of the forces about any point is equal to zer..

A rigid body is said to be in equilibrium if, both the linear and angular momentum of a rigid body have a constant value. For the equilibrium of a rigid body, the body need not be at rest. However, if it is at rest, it is called the static equilibrium. Conditions for the rigid body to be at equilib..

A good illustration of the ideas discussed in this chapter is the motion of a cart pulled by a horse. Suppose the cart is at rest when the driver whips the horse. The horse pulls the cart and the cart accelerates forward. The question posed is as follows. The horse pulls the cart with a force..

Dalton's law of partial pressure says that the pressure exerted by a mixture of several gases or vapors (which do not interact in any) equals the sum of the pressures exerted by each gas occupying the same volume as that of the mixture. In Kinetic theory, we assume that the pressure exert..

x = 1 kg Let us take another example of two boys carrying a load on a stick between them as shown in figure below. Let us calculate what part of the load each boy carries. To find the upward force exerted by the boy at A, we shall consider the hand of the boy at B as the pivot. Now, the c..

Principle of Moments - If a body is in equilibrium under the action of a number of forces, then the algebraic sum of the moments of the forces about any point is equal to zero. In other words, the sum of the clockwise moments equals sum of the antic..

Question: The force of gravitation between two bodies in the universe does not depend on 1. the distance between them 2. the product of their masses 3. the sum of their masses 4. the gravitational constant Answer: ..
