Answer:
The point that would have the same electric field as P is from the center of the sphere.
Explanation:
From the question we are told that
The radius of the sphere is
The Electric field at point P is
The distance of point P from the center is
Since the electric is directed radially outward it mean this it would be felt both inside and outside the sphere
The Electric field inside the sphere at a distance z is mathematically represented as
where k is the coulomb's constant with a value
q is the charge
The Electric field inside the sphere at a distance D is mathematically represented as
To obtain the point of equal electric field
We have that
Substituting values
Explanation:
(b) We know that,
1 day = 24 hours
1 hour = 3600 s
So, we found that, 1 day = 86400 s
We need to find the 360 days into seconds. So,
1 day = 86400 s
360 days = 86400×360
360 days = 31104000 seconds
(d) Weight of a body, W = 600 N
Acceleration due to gravity on mars is 3.7 m/s²
Weight, W = mg
m is mass of body
(e) Mass of body, m = 100 kg
Acceleration due to gravity on the moon, 1.6 m/s²
Weight, W = 100 × 1.6
W = 160 N
