If F→$$1$$ force is removed, then the acceleration becomes $$7$$ $$m/s2$$ in north, then the acceleration of the block if only F→$$1$$ is acting will be

Question

Five forces F→$$1$$,F→$$2$$,F→$$3$$,F→$$4$$ and F→$$5$$, are acting on a particle of mass $$2.0$$ kg so that it is moving with $$4$$ $$m/s2$$ in east direction. If F→$$1$$ force is removed, then the acceleration becomes $$7$$ $$m/s2$$ in north, then the acceleration of the block if only F→$$1$$ is acting will be

Infinity Learn · Accepted Answer

F→$$1+F$$→$$2+F$$→$$3+F$$→$$4+F$$→$$5=2(4i^)$$     .......(i)and$$    F→$$2+F$$→$$3+F$$→$$4+F$$→$$5=2(7j^)   ........(ii) From (i) and (ii), F→$$1=8i^$$−$$14j^a$$→$$1=F$$→$$1m=4i^$$−$$7j^$$⇒ $$a1=16+49=65m/s2$$
