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
