Question:
In the electroweak theory, symmetry breaking occurs on a length scale of about 10-17 m. Compute the frequency of particles with de Broglie wavelengths (see Section 10.5) equal to this value, and, using this result, determine their energies by the Planck formula E = hf. Show that the mass of particles having such energies is on the order of the mass of the W± particles (Figure 12.23).

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
