Answer:
The force exerted by three charges on the fourth is
Explanation:
Given:
- The magnitude of three identical charges,
- Length of the edge of the square a=3 cm
- Magnitude of fourth charge ,Q=3 nC
According to coulombs Law the force F between any two charge particles is given by
where r is the radial distance between them.
Since the force acting on the charge particle will be in different directions so according to triangle law of vector addition
Answer:
It will take about 1.32 seconds to travel to his location.
Explanation:
Considering the sound travels at 340 m/s, then if a person is at a distance of 450 m m from the bell, we can use the velocity formula to find the answer;
