Pada artikel ini Anda akan menemukan pengertian massa jenis permukaan, rumusnya, dan contoh penghitungan massa jenis permukaan suatu benda. Selain itu, ini menjelaskan apa itu kepadatan muatan permukaan. <\/p>\n

<\/span> Berapakah kepadatan permukaan?<\/span><\/h2>\n

Massa jenis areal<\/strong> , disebut juga massa jenis per satuan luas<\/strong> , adalah perbandingan massa terhadap luas permukaan suatu benda. Dengan kata lain, kepadatan permukaan adalah jumlah massa per satuan luas.<\/p>\n

Istilah kerapatan permukaan terutama digunakan dalam elektromagnetisme untuk menghitung medan listrik yang dihasilkan oleh suatu permukaan. Kami akan kembali ke konsep ini secara lebih rinci di bawah. <\/p>\n

<\/span> Rumus kepadatan permukaan<\/span><\/h2>\n

Massa jenis permukaan sama dengan massa suatu benda dibagi luas permukaan benda tersebut.<\/strong><\/p>\n

Oleh karena itu, rumus kerapatan permukaan adalah sebagai berikut:<\/p>\n

\n

\"\\sigma=\\cfrac{m}{A}\"<\/p>\n<\/p>\n

Emas<\/p>\n

\"\\sigma\"<\/p>\n

adalah kepadatan permukaan,<\/p>\n

\"m\"<\/p>\n

massa benda dan<\/p>\n

\"A\"<\/p>\n

total luas permukaan benda.<\/p>\n

Misalnya massa suatu benda 15 kg dan luas permukaannya 3,5 m 2<\/sup> , maka perhitungan massa jenis permukaannya dilakukan sebagai berikut:<\/p>\n

\n

\"\\sigma=\\cfrac{m}{A}=\\cfrac{15}{3.5}=4.29<\/p>\n<\/p>\n

Anda harus ingat bahwa massa jenis volumetrik biasanya dihitung, karena benda memiliki tiga dimensi. Oleh karena itu disarankan untuk mengetahui cara menghitungnya: <\/p>\n

<\/span> Kepadatan muatan permukaan<\/span><\/h2>\n

Terakhir, dalam bidang elektromagnetisme, massa jenis permukaan mempunyai arti yang berbeda, karena massa jenis tidak mengacu pada massa suatu benda tetapi pada jumlah muatan listrik yang dimilikinya.<\/p>\n

Kerapatan muatan permukaan<\/strong> adalah banyaknya muatan listrik pada suatu benda per satuan luas permukaan. Oleh karena itu, kerapatan muatan permukaan dihitung dengan membagi muatan listrik suatu benda dengan luas permukaannya.<\/p>\n

\n

\"\\sigma=\\cfrac{Q}{A}\"<\/p>\n<\/p>\n

Emas<\/p>\n

\"\\sigma\"<\/p>\n

adalah kerapatan muatan permukaan,<\/p>\n

\"Q\"<\/p>\n

muatan listrik benda dan<\/p>\n

\"A\"<\/p>\n

permukaannya. <\/p>\n
