E = sigma/2 * epselon naught
E = 300 * 10^-9/(2 * 8.854 * 10^-12)
E = 1.7 * 10^4 N/C
Assuming that the electric field is uniform all across the surface:
Then, Electric flux = E * A
Electrix flux = 1.7 * 10^4 * 15 = 2.5 x 10^5 Nm^2/C
It should be b)
Answer:
Net force = 25N and in the right direction
Explanation:
mass of box, m = 50kg
Force of block = 150N
Friction force = 125N
150 - 125 = 25N
the force applied to the block is greater than the friction force. there the force applied will overcome the friction force and move in the right direction of the force applied
Answer:
It takes the motorcycle about 12.65 seconds to reach 100mph
Explanation:
Answer:
Experiments showed that increasing the light frequency increased the kinetic energy of the photoelectrons, and increasing the light amplitude increased the current.
Explanation:
The photocurrent increases linearly with the intensity of the incident light but is independent of its frequency. The stopping potential increases linearly with the frequency of the incident light but is independent of its intensity.
