When forces \[{{F}_{1}},\,{{F}_{2}},\,{{F}_{3}}\] are acting on a particle of mass m such that \[{{F}_{2}}\] and \[{{F}_{3}}\] are mutually perpendicular, then the particle remains stationary. If the force \[{{F}_{1}}\] is now removed then the acceleration of the particle is [AIEEE 2002] |
A. | \[{{F}_{1}}/m\] |
B. | \[{{F}_{2}}{{F}_{3}}/m{{F}_{1}}\] |
C. | |
D. | \[{{F}_{2}}/m\] |
