Gauss's law is usualy written as :
∫φ_e = e * da= qencl / ε0
what does qencl refers in guass's law?
o the net charge inside the closed surface
o the charge residing on insulators inside the closed surface
o all the charge in the physical system
o any charge inside the closed surface that is arranged symmetrically

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant
