Question

The acceleration due to gravity at the poles
is 10ms-2 and equatorial radius is 6400km for
the earth. Then the angular velocity of rotation
of the earth about its axis so that the weight
of a body at the equator reduces to 75% is
ANSWER IS 1/1600
Can u solve me plzzzzzzzz​

Answer 1

Answer:

Then the angular velocity of rotaiton of the earth about its axis so that the weight of a body at the equator reduces to 75% is. ... due to gravity at the poles is 10ms-2 and equitorial radius is 6400km for the earth. ... 11600rads-1 ... What should be the velocity of earth due to rotation about its own axis so that.
