```										(a) Tension in the string in Equilibrium
T cos 60° = mg
⇒ T = mg/cos 60° = 10 * 10^-3 * 10/1/2 = 10^-1 * 2 = 0.20 N
(b) Straingtening the same figure
Now the resultant for ‘R’
Induces the acceleration in the pendulum.
T = 2 * π √ℓ/g = 2π √ℓ/[g^2 +(σq/2ε base 0m)^2]^1/2 = 2π √ℓ/[100 +(0.2 * √3/2 * 10^-2)^2]^1/2
= 2π √ℓ/(100 + 300)^1/2 = 2π √ℓ/20 = 2 * 3.1416 * √10 * 10^-2/20 = 0.445 sec.
