A body is at rest under the action of three forces, two of which are `vec(F)_(1)= 4hat(i), vec(F)_(2)= 6hat(j)`, the third force is

If vec(F) = (5hat(i)+2hat(j) - 4hat(k))N , the magnitude of force is

During displacement of a body two forces are acting on it simultaneously. Forces are vec(F_(1))=(2hat(i)-2hat(j)),vec(F_(2))=(hat(i)+5hat(j)) . Work done by individual force on body is (-8"Joule") and (2 Joule) respectively then displacement of body will be

An object is acted upon by the forces vec(F)_(1)=4hat(i)N and vec(F)_(2)=(hat(i)-hat(j))N . If the displacement of the object is D=(hat(i)+6hat(j)-hat(k)) m, the kinetic energy of the object

An object is acted upon by the forces vec(F)_(1)=4hat(i)N and vec(F)_(2)=(hat(i)-hat(j))N . If the displacement of the object is D=(hat(i)+6hat(j)-hat(k)) m, the kinetic energy of the object

Following forces start acting on a particle at rest at the origin of the co-ordinate system simultaneously vec(F)_(1)= -4hat(i)-5hat(j)+5hat(k), vec(F)_(2)= 5hat(i)+8hat(j)+6hat(k), vec(F)_(3)= -3hat(i)+4hat(j)-7hat(k) and vec(F)_(4)= 2hat(i)-3hat(k) then the particle will move

A body of mass 1 kg begins to move under the action of a time dependent force vec(F) =(2t hat(i)+3t^(2)hat(j)) N . Where hat(i) and hat(j) are unit vectors along X and Y axis . What power will be developed by the force at the time t .

Following forces start acting on a particle at rest at the origin of the co-ordinate system simultaneously vec(F)_(1)=-4hat(i)+5hat(j)+5hat(k), vec(F)_(2)=-5hat(i)+8hat(j)+6 hat(k), vec(F)_(3)=-3 hat(i)+4 hat(j)-7hat(k) and vec(F)_(4)=12hat(i)-3hat(j)-2hat(k) then the particle will move-

Following forces start acting on a particle at rest at the origin of the co-ordinate system simultaneously vec(F)_(1)=-4hat(i)+5hat(j)+5hat(k), vec(F)_(2)=-5hat(i)+8hat(j)+6 hat(k), vec(F)_(3)=-3 hat(i)+4 hat(j)-7hat(k) and vec(F)_(4)=12hat(i)-3hat(j)-2hat(k) then the particle will move-
