Answer: 4.27 *10^6 N/C
Explanation: In order to calculate the electric field along the axis of charged ring we have to use the following expression:
E=k*x/(a^2+x^2)^3/2 where a is the ring radius and x the distance to the point measured from the center of the ring.
Replacing the data we have:
E= (9* 10^9* 0.3* 50 * 10^-6)/(0.1^2+0.3^2)^3/2
then
E=4.27 * 10^6 N/C
Answer:
Explanation:
Arrangement of all known elements to men based on state of matter reactivity and valence shell structure
Answer:
20 N exerts no torque about the pivot.
14 N exerts a counterclockwise torque of 14 * .3 = .42 N-m
6 exerts a clockwise torque of 6 * .7 = .42 N-m
The meter stick will not turn because there is no net torque on the meter stick.
Answer:
When force and displacement are in the same direction, the work performed on an object is said to be positive work. Example: When a body moves on the horizontal surface, force and displacement act in the forward path. The work is done in this case known as Positive work.
