Question

If the height of transmitting and receiving antennas are 80 m each, the maximum line of sight distance will be. Given: Earth’s radius = 6.4 × 10⁶ m.

G1 Physics · Accepted Answer

Maximum line-of-sight distance is d = √(2Rh₁) + √(2Rh₂). With h₁ = h₂ = 80 m and R = 6.4 × 10⁶ m, d = 2√(2×6.4×10⁶×80) = 64 km.
