In my knowledge
Option B. Lava flowed from the moon
and I am pretty sure cause I have read about it and option B is the conclusion I came with lol :D
Ignoring air resistance . . .
After the bomb is released, tangential (horizontal) acceleration is zero,, normal (vertical) acceleration is 9.8 m/s^2 down (gravity).
Answer:
Now e is due to the ring at a
So
We say
1/4πEo(ea/ a²+a²)^3/2
= 1/4πEo ea/2√2a³
So here E is faced towards the ring
Next is E due to a point at the centre
So
E² = 1/4πEo ( e/a²)
Finally we get the total
Et= E²-E
= e/4πEo(2√2-1/2√2)
So the direction here is away from the ring
Answer = 1000N
F = ma
M = 500kg
a= 2 m/s/s
Solve for F
