A ball is thrown upward with an initial velocity V₀ from the surface of the earth. The motion of the ball is affected by a drag force equal to mγν²(where m is mass of the ball, v is its Instantneous velocity and γ is a constant). Time taken by the ball to rise to its zenith is:(A) {1/√(γg)} ln{1+ √(γ/g) V₀}(B) {1/√(γg)} tan⁻¹{√(γ/g) V₀}(C) {1/√(γg)} sin⁻¹{√(γ/g) V₀}(D) {1/√(γg)} tan⁻¹{√(γ/g) V₀} |
