A string has a mass \( 10 \mathrm{~g} \) and a length \( L=3 \mathrm{~m} \). Its two ends are tied to two walls a distance \( d=2 \mathrm{~m} \) apart. Two blocks, each of mass \( m=2 \mathrm{~kg} \), are suspended from the string as shown in the figure. In what time will a wave pulse sent from a point \( P_{1} \) reach point \( P_{2} \) ?
(a) \( 52.9 \mathrm{~ms} \)
(b) \( 42.9 \mathrm{~ms} \)
(c) \( 32.9 \mathrm{~ms} \)
(d) \( 22.9 \mathrm{~ms} \)
