Dear Student, let the accn be aa=FM+mlet the tension be T ma=TcosθT=macosθ=FmM+mcosθRegards

sir
sir 7. Two blocks of masses m and M are connected by an inextensible light string. When a constant horizont force acts on the block of mass M. The tension in the string is m (M + m)cosO (3) (m + M)cos0 (2) (M + m)sin0 (4) (M + m)sinO

Dear Student,
