A 0.1 kg block suspended from a massless string is moved
first vertically up with an acceleration of 5ms⁻² and then
moved vertically down with an acceleration of 5ms⁻² . If
T₁ and T₂ are the respective tensions in the two cases,
then
(a) T₂ > T₁(b) T₁ - T₂ = 1 N, if g = 10ms⁻²
(c) T₁ -T₂ = 1kg f
(d) T₁ - T₂ = 9.8N, if g = 9.8 ms⁻²
