A block P of mass 0.4 kg is attached to a vertical rotating spindle by two strings AP and BP of equal length 1.0 m as shown in the figure. The period of rotation is 1.2 s . Tensions T1\mathrm{T}_1 and T2\mathrm{T}_2 in string AP and BP are A block P of mass 0.4 kg is attached to a vertical rotating spindle by two strings AP and BP of equal length 1.0 m as

Options

  1. AT1=15.86 N T2=10.97 N\mathrm{T}_1=15.86 \mathrm{~N} \quad \mathrm{~T}_2=10.97 \mathrm{~N}
  2. BT1=15.86 N T2=3.04 N\mathrm{T}_1=15.86 \mathrm{~N} \quad \mathrm{~T}_2=3.04 \mathrm{~N}
  3. CT1=7.94 N T2=3.03 N\mathrm{T}_1=7.94 \mathrm{~N} \quad \mathrm{~T}_2=3.03 \mathrm{~N}
  4. DT1=T2=5.48 N\mathrm{T}_1=\mathrm{T}_2=5.48 \mathrm{~N}

Correct answer

C. T1=7.94 N T2=3.03 N\mathrm{T}_1=7.94 \mathrm{~N} \quad \mathrm{~T}_2=3.03 \mathrm{~N}
