Answer:
0.5 m/s2
Explanation:
accelration formula : final velocty - starting velocity divided by time
Answer:
C. outside 45 degrees
Step-by-step explanation:
C. outside 45 degrees
because it can be any point or direction outside 45 degrees
Explanation:
Charges,![q_1=8\ \mu C=8\times 10^{-6}\ C](https://tex.z-dn.net/?f=q_1%3D8%5C%20%5Cmu%20C%3D8%5Ctimes%2010%5E%7B-6%7D%5C%20C)
![q_2=-5\ \mu C=-5\times 10^{-6}\ C](https://tex.z-dn.net/?f=q_2%3D-5%5C%20%5Cmu%20C%3D-5%5Ctimes%2010%5E%7B-6%7D%5C%20C)
The distance between charges, r = 10 cm = 0.1 m
We need to find the magnitude and direction of the electric force. It is given by :
![F=\dfrac{kq_1q_2}{r^2}\\\\F=\dfrac{9\times 10^9\times 8\times 10^{-6}\times 5\times 10^{-6}}{(0.1)^2}\\\\F=36\ N](https://tex.z-dn.net/?f=F%3D%5Cdfrac%7Bkq_1q_2%7D%7Br%5E2%7D%5C%5C%5C%5CF%3D%5Cdfrac%7B9%5Ctimes%2010%5E9%5Ctimes%208%5Ctimes%2010%5E%7B-6%7D%5Ctimes%205%5Ctimes%2010%5E%7B-6%7D%7D%7B%280.1%29%5E2%7D%5C%5C%5C%5CF%3D36%5C%20N)
So, the required force between charges is 36 N and it is towards positive charge i.e. +8 μC.
as the surface area increases the rate of reaction also increases.
