0.5
Explanation:
number of squash seeds = 3
Number of bean seeds = 3
Total number of seeds = 3 + 3 = 6
Number of seed selected = 1
Chance to find that the seed is of bean seed
Number of ways to select a bean seed from bean seeds = 3 C 1
=
Number of ways to select a seed from all the seeds = 6 C 1
= \frac{6!}{1!\times5!}=6
So, the chance that it is a bean seed = 3 / 6 = 1/2 = 0.5
-606.73C
Explanation:
According to coulombs law
F = kq1q2/r^2
Substitute the given value
83,506 = 9*10^9(-0.198)q2/(3004)^2
83,506 = -1.242*10^9q2/9,024,016
-1.242*10^9q2 = 7.54*10^11
q2 = -7.54*10^11/1.242*10^9
q2 = -606.73C
hence the magnitude of the other charge is -606.73C
