Answer: Option (b) is the correct answer.
Explanation:
Since, there is a negative charge present on the ball and a positive charge present on the rod. So, when the negatively charged metal ball will come in contact with the rod then positive charges from rod get conducted towards the metal ball.
Hence, the rod gets neutralized. But towards the metal ball there is a continuous supply of negative charges. Therefore, after the neutralization of positive charge from the rod there will be flow of negative charges from the metal ball towards the rod.
Thus, we can conclude that negative charge spread evenly on both ends.
Answer:
The magnitude of the hiker’s resultant displacement is 5.6 km
The direction of the hiker’s resultant displacement is 77 degrees south west! Hope this helps!!!
The last choice is your answer, I just did it.
force= mass × acceleration
1km=10^3 m,1km^3=10^9cubic metres answer is 1.4x10^18cubic meters
