At a distance of 0.182 cm from the center of a charged conducting sphere with radius 0.100cm, the electric field is 465 n/c . what is the electric field 0.598 cm from the center of the sphere?

By Gauss" Law E = K Q / R^2  where R is measured from the center

of the sphere.   (in this case the field is zero inside the sphere, why?)

So E2 / E1 = R1^2 / R2^2    with K and Q cancelling

E2 = E1 * (R1 / R2)^2 = 465 nc * (.182 / .598)^2 = 43.1 n/c

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.
