A solid conducting sphere of radius a is surrounded by a layer of linear dielectric between a < r < b . The linear dielectric has a non-uniform dielectric constant. A grounded very thin conducting shell coats the outer surface of the linear dielectric at radius b. Find the displacement field D in the region a < r < b.

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

explanation:

i tried it and took the test

if im wrong then we have different tests
