Decreases
Explanation:
The acceleration due to gravity on a body decreases with depth.
Acceleration due to gravity is the change in velocity with time of a body as result of the pull of gravity or gravitational force.
- The acceleration due to gravity tend to pull all bodies to the center of the earth.
- As body moves away from the center of the earth, the pull becomes very more and acceleration increase.
- But when a body approaches the center of the earth, the acceleration reduces.
- At depth, the acceleration due to body of a body begins to decrease.

Solution :
Let us consider the Gaussian surface that is in the form of a cylinder having a radius of r and a length of A which is
.
The charged enclosed by the cylinder is given by,
(here, V =
is the volume of the cylinder)
If
is positive, then the electric field lines moves in the radial outward direction and is normal to Gaussian surface which is distributed uniformly.
Therefore, total flux through Gaussian cylinder is :


Now using Gauss' law, we get

or 
Therefore, the electric field is 
Hence, option (d) is correct.
The distance is 1760 km
The speed is 960 km hour I.e 960 divide by 60 = 16 km/minute
hence in time 1 hour 50 minutes I.e 110 minutes
distance travelled is 110 - 16 = 1760 km
