Answer:
i) E = 269 [MJ] ii)v = 116 [m/s]
Explanation:
This is a problem that encompasses the work and principle of energy conservation.
In this way, we establish the equation for the principle of conservation and energy.
i)
At that point the speed 1 is equal to zero, since the maximum height achieved was 2.5 [km]. So this calculated work corresponds to the energy of the rocket.
Er = 269*10^6[J]
ii ) With the energy calculated at the previous point, we can calculate the speed developed.
Let 10 nC and 20 nC charge is placed at "d" distance
now let say we will have a point at distance "x" from 10 nC at which electric field will be zero
now we will have
now plug in all data
square root both sides
so yes there will exist a point between 10 nC and 20 nC charge at which electric field will be zero
