In the given arrangement, n number of equal masses areconnected by strings of negligible masses. The tension inthe string connected to nth mass is-Q.127TTT77mMgmMg(C) mg(D) mng

Answer»

T=nm*a=ma..........eq 1

Mg-T=maMg-mna

=maMa+mna

=mga(M+nm)

=mga=mg/m+nm

Sub a valve in eq 1

T=nm*a

T=nm*mg/M+nm

Option a is correct na
