Answer:
a. dW = ∫pEsinθdθ b. W = p.E
Explanation:
a. We know torque τ = p × E = pEsinθ where θ is the angle between p and E
Let the torque τ rotate the dipole by an amount dθ. So, the workdone dW = ∫τdθ = ∫pEsinθdθ
b. So, the total work done is gotten by integrating from 90 to θ. So,
W = ∫₉₀⁰dW
= ∫₉₀⁰pEsinθdθ
= pE∫₉₀⁰sinθdθ
= pE(cosθ - cos90)
=pEcosθ
= p.E
Formula of range is given by

here given that

θ=14.1∘

now by above equation

R = 66.7 m
so range will be 66.1 m
Answer:
the acceleration of an object is directly pro to the net force acting on it and indirectingly proportional to its mass
Answer:
C. position
Explanation:
potential energy is based on stored energy, therefore it is C
The object increases in speed
