Answer:

q = 4.5 nC

Explanation:

given,

electric field of small charged object, E = 180000 N/C

distance between them, r = 1.5 cm = 0.015 m

using equation of electric field

E = \dfrac{kq}{r^2}

k = 9 x 10⁹ N.m²/C²

q is the charge of the object

q= \dfrac{Er^2}{k}

now,

q= \dfrac{180000\times 0.015^2}{9\times 10^9}

      q = 4.5 x 10⁻⁹ C

      q = 4.5 nC

the charge on the object is equal to 4.5 nC

Answer:

The charge on the object is 4.5\times10^{-9}\ C

Explanation:

Given that,

Electric field = 180000 N/C

Distance = 1.5 cm

We need to calculate the charge on the object

Using formula of electric field

E=\dfrac{kq}{r^2}

Where, q = charge

r = distance

Put the value into the formula

180000=\dfrac{9\times10^{9}\times q}{(1.5\times10^{-2})^2}

q=\dfrac{180000\times(1.5\times10^{-2})^2}{9\times10^{9}}

q=4.5\times10^{-9}\ C

Hence, The charge on the object is 4.5\times10^{-9}\ C
