Answer:
The torque on the lever is 30.0 N m.
Explanation:
Torque is defined as tendency of a force to rotate a body around its axis. Mathematically written as:
Force applied on the lever arm at 90°= 15 N
Distance at which force is applied = d = 2.0 m
The torque on the lever is 30.0 N m.
Answer:
E = 1000 x
Explanation:
The electric potential and the electric field are related by the formula
dV = - E . dx
Bold represents vectors.
The point represents the scalar product, in this case we calculate the electric field in the x-axis and the potential is also in this axis so the scalar product is reduced to the algebraic product
E = dV /dx
Let's make the derivative
E = - 2ax
Let's replace the values
E = -2 (-500) x
E = 1000 x
10.0 force to get 2000j to move a box in 8s.
