1.	a Bob of mass 100 gram is suspended from the ceiling of trolley 900 gram if the trolley accelerates horizontally then string makes an angle theta is equal to 30 degree with the vertical value of force needed to provide this acceleration to trolley will be (1) 5.7N (2) 2.85N (3)5.13N (4)3.13N
Answer» (1) 5.7 NExplanation:1) Considering the situation with respect to lift : SINCE, bob is in equilibrium with respect to lift.That is ,2) Dividing above two equation we got,3) Now, FORCE NEEDED to get this acceleration is HENCE, Required answer is (1) 5.7 N
