Question

Define rectilinear motion and curvilinear motion???​

Answer 1

Explanation:

a linear motion in which the direction of the velocity remains constant and the path is a straight line.

eg. a car on a highway

The motion of an object moving in a curved path is called curvilinear motion.

eg. A stone thrown into the air at an angle

Answer 2

An isotropic material of relative permittivity is placed normal to a uniform external electric field with an electric displacement vector of magnitude 6 * 10-4 C/m2 . If the volume of the slab is 0.7 m3 and magnitude of polarization is 5 *10-4 C/m2 . Find the value of PERMITTIVITY and total dipole moment of the slab.
