The direction of the electric field would be south.
qE/m = 115
<span> E = 115*m/q </span>
<span> = 115 * 9.1 * 10^(-31) / 1.67*10^(-19) </span>
<span> = 762.87 * 10^(-12) </span>
<span> = 6.27 x 10^-10 N/C
</span>
Hope this answers the question. Have a nice day. Feel free to ask more questions.

Answer:
Explanation:
Radius of the ball is
Initial speed of the ball is
Initial angular speed of the ball is
Coefficient of kinetic friction between the ball and the lane
is
Due to the presence of frictional force, ball moves with
decreasing velocity.
(a)
velocity in terms of is
(b)
Ball's linear acceleration is given by
(c)
During sliding, ball's angular acceleration is calculated as
(d)
The time for which the ball slides is calculated from the
equation of motion is
(e)
Distance traveled by the ball is
(for)
The speed of the ball when smooth rolling begins is
I believe it is 17 hope it helps!
