Question

Two masses A and B each of mass M are fixed together by a massless spring. A force acts on the mass B as shown. At any instant mass A has acceleration a, the acceleration of mass B is (A) (F/M) - a (B) (F/2M) (C) (F/M) + a (D) a

Tardigrade Admin · Accepted Answer

Net force on B = F - Ma Acceleration of B = (F/M) - a

Q. Two masses A and B each of mass M are fixed together by a massless spring. A force acts on the mass B as shown. At any instant mass A has acceleration a, the acceleration of mass B is

$\frac{F}{M} - a$

$\frac{F}{2 M}$

$\frac{F}{M} + a$

$a$

Net force on B = F - Ma
Acceleration of B = $\frac{F}{M} - a$

MF​−a

2MF​

MF​+a

a

Net force on B = F - Ma Acceleration of B = MF​−a

$\frac{F}{M} - a$

$\frac{F}{2 M}$

$\frac{F}{M} + a$

$a$

Net force on B = F - Ma
Acceleration of B = $\frac{F}{M} - a$
