Answer:

B) 3/4 Rω

²

Explanation:

Radius of the earth = R (Given)

Value of acceleration = g30 (Given)

Angle of latitude = 30°(Given)

Acceleration due to gravity at latitude  λ  is expressed as -

g' = g−Rω²  cos²λ

Thus at the degree of 30° it will be -

g30  =  g−Rω²  cos²30°

= g-3/4 Rω²

Thus the value of g-g₃₀ is = 3/4 Rω²
