The force of gravity = GMm / r^2, where G is gravitational constant, M is mass of one object, m is mass of another object, r is distance between them.
To make gravity smaller, decrease mass or increase distance.
To make gravity bigger, increase mass or decrease distance.
Answer:
False
Explanation:
In the question it is given that a proton travels in the right moves in between the two plates. An electric field that is pointing in the vertically upward direction has magnitude of 3 N/C. The electric field is produced by the plates.
Now from here we can conclude that the direction of the force acting on the proton when the proton is in between the plates acts in the downward direction. While the electric field lines points in the upward direction. Thus the electric point will not be in the direction of the force that acts on the proton.
The answer to your question is: Yes.
To solve each and every one, write the two given numbers in place of their letters in the given equation, and then solve the equation for the letter that's left.
For example, let's do #1 together. I'll do all the work, and you just watch.
#1 says that s=d/t. It also tells us that 'd' is 4 and 't' is 2. So here's a great idea: Why don't we write '4' where it says 'd', and write '2' where it says 't', and then see what we've got ?
s = 4/2
Wow ! We know that 4/2 is 2 . So s=2 and that's exactly the answer to the question !
Now it's YOUR turn. Do the next 25 problems the same way.
