The diagram represents two small charged spheres, A and B, 3 meters apart. Sphere A has a charge of -2.0 × 10^-6 C. Sphere B has a charge of +2.0 × 10^-6 C. Which diagram best illustrates the electric field between charges A and B?

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

correct it is c.) b b

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
