Question

B
A->
Three identical blocks of mass
2kg each are connected by ideal
strings and one of block is applied
by a force 12N.The setup is kept
on a smooth horizontal
surface. Then. Normal from the
ground on Block A has the value (
Take g = 10 m/s^2)​

Answer 1

Answer:

Given,

Mass of A, B and C m

a

=m

b

=m

c

=2kg

Acceleration of system, a=

(m

a

+m

b
