When neutral charge comes into contact with a positive charge

If they come in direct contact, then with certain restrictions, the neutral charge  will experience a transfer of 1/2 a charge from the positive body providing we're talking about a large enough charge that can be transferred.

So if one sphere starts with no charge and one with 6 * 10^-14 Q, if they touch,then each sphere will have a charge of 3*10^-14 Q which is still a pretty big charge.

dang that balls went far

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
